Communication security of intelligent information service platform combining AES and ECC algorithms

ABSTRACT The rapid progress of information technology has made the status of information service platforms increasingly prominent in social operations. However, their communication security is also facing unprecedented challenges. In response to the issues of insufficient security and efficiency in traditional encryption algorithms, this study combines advanced encryption standard algorithms with elliptic curve cryptography algorithms to generate encryption key pairs through elliptic curve cryptography algorithms. It utilizes advanced encryption standard algorithms to generate symmetric keys, and then encrypts the keys of the advanced encryption standard using the public key of the elliptic curve cryptography algorithm. Based on this, it implements advanced encryption standard encryption on data and designs a hybrid encryption algorithm. The results showed that the throughput of this method was 4000bit/s, with a delay of 550 m, which is higher than other algorithms, proving its high efficiency in processing data. The average bit change of the ciphertext in the hybrid encryption algorithm was 55.8 bits, with a range of bit changes of [69.3, 82.7], which is significantly higher than other algorithms, proving its high security. The designed algorithm has significant benefits in communication security of information service platforms and plays an important role in promoting the development of future network security defense technology.

Encryption of messages by the sum of a real variable functions.

The article proposes a cryptosystem with symmetric keys, where the keys are functions of a real variable. These functions can be either continuous or discrete and must satisfy certain constraints. The number of key functions is determined by the number of binary digits that encode a character in the ASCII table. Each binary digit has its own key function. The cipher of a character is represented by a one-dimensional array of real numbers. These numbers are obtained by summing the key functions, which correspond to “1” in the ASCII code of the character. The amplitudes of these functions are random and unknown to the receiving party. Decryption is a multi-level process, in which integral disproportion functions are calculated at each level. To increase the cryptographic strength, the encryption/decryption process involves a permutation of the key-functions according to a secret scheme agreed upon by both parties. Computer simulation has demonstrated the high cryptographic resistance of the proposed system to the determination of the coefficients within the key functions, as well as to the rearrangement of the key functions themselves. It is shown that adjacent identical symbols in an encrypted message have different ciphers, which also complicates hacking the system.

Audio encryption framework based on chaotic map and DNA encoding

In this work, an audio encryption framework is proposed based on the chaos theory and DNA encoding. Traditional encryption algorithms designed for text data might not be efficient for handling the bulk data of audio files, leading to slow processing times and increased storage requirements. Striking the right balance between robust encryption and efficient processing is crucial. Additionally, some encryption methods can introduce noise or artifacts into the audio signal, impacting its clarity. Maintaining high-fidelity audio quality while ensuring strong encryption remains an ongoing area of research. Despite these challenges, the need for secure audio communication is undeniable. The RCM chaotic map is used to introduce chaotic properties in the encryption framework. A novel pseudorandom bit generator approach is proposed and used for encryption purposes. The proposed work is a symmetric encryption approach and is completely lossless. The proposed approach uses some lightweight computational procedures that make the algorithm simple and computationally less expensive which makes it suitable for real-time applications. Furthermore, the proposed approach shows significant performance and resilience against various cryptographic attacks. A new scrambling algorithm is proposed to add a layer of security. The proposed scramble algorithm uses logistic map beside the RCM map. The proposed approach achieved 98.28 % NSCR value and 33.63 % UACI values on average. The experimental outcomes are encouraging for practical applications of the proposed approach.

A hybrid encryption approach for efficient and secure data transmission in IoT devices

Security is a crucial concern in the Internet of Things (IoT) ecosystem. Due to IoT devices' constrained processing and storage resources, providing reliable security solutions is challenging. Encryption is one of the most commonly used techniques to secure user data against unauthorized access. Therefore, it is essential to develop encryption solutions that have minimal impact on the performance of IoT devices. This study introduces a hybrid encryption approach that combines symmetric blowfish encryption with asymmetric elliptic curves. Blowfish encryption is used to encrypt large volumes of data, which could otherwise affect the execution time.In contrast, elliptic curve cryptography is utilized to ensure the security of the private key, which has a small size and does not increase the execution time significantly. The suggested approach provides advantages of both asymmetric and symmetric encryption methods, leading to an improvement in throughput and a reduction in execution time. The proposed approach was evaluated, yielding promising results in comparison to other cryptographic algorithms. The results show the optimization of more than 15% in the execution time and the efficiency increase by the proposed solution. This improvement represents security with the least impact on processing resources.

CoD-DSSE: A practical efficient dynamic searchable symmetric encryption with lightweight clients

Dynamic searchable symmetric encryption(DSSE) combines dynamic update with searchable encryption, allowing users to not only achieve keyword retrieval, but also dynamically update encrypted data stored on semi-trusted cloud server, effectively protecting user’s privacy. However, the majority of existing DSSE schemes exhibit inefficiencies in practical applications because of their complex structure. In addition, to store the status of keywords, the storage requirements of the client increase proportionally with the number of keyword/document pairs. Therefore, the client storage will be overwhelmed when confronted with a substantial increase in the volume of keyword/document pairs. To solve these issues, we propose a practical efficient dynamic searchable symmetric encryption scheme with lightweight clients—CoD-DSSE. A novel index structure similar to a chest of drawers is proposed in CoD-DSSE, which allows users to efficiently search all document indexes through XOR operations and keeps the keyword status on the server to lightweight clients. Furthermore, we use a random number generator to construct new search tokens for forward security and achieve backward security by using a Bloom filter to store the deleted document index, which can significantly reduce communication costs. The experimental and security analyses show that CoD-DSSE is efficient and secure in practice.

Justification of methods for calculating and analyzing the properties of pseudorandom and random sequences based on DNA

An integral requirement for modern information systems is to provide users with services such as confidentiality, integrity, availability, and irrefutability. The quality of such services directly depends on cryptographic transformations, an important component of most of which is randomness. Therefore, the generation of pseudorandom and random sequences is one of the most relevant and important tasks in cryptography. Such sequences are generated based on physical and non-physical noise sources. Our previous studies indicate the theoretical possibility to use DNA as a noise source and, accordingly, as a source of random sequences. Any noise source "contains randomness", i.e. it has a certain amount of entropy, but a sample from such a source will not always have good properties. That is why there is a need for tools that can obtain sequences with good randomness properties of samples from the DS sequences with good randomness properties of samples from the noise source (by, for example, some kind of enhancement). Such sequences should satisfy the necessary conditions: be statistically indistinguishable, uniform, etc. NIST-approved DRBG designs can be used to guarantee this. Such constructions are most often based on strong crypto-primitives, such as hashes, HMACs, or block or stream ciphers in the required modes. This work is devoted to newly developed methods for obtaining pseudorandom and random sequences based on DNA sequences using the national standard for block symmetric encryption DSTU 7624:2014 in the counter (CTR) operation mode, as well as methods for comparing sequences (both DNA and binary). The work essentially opens the topic of obtaining random sequences based on DNA, since previous studies of DNA in cryptography have focused on the use of DNA in encryption and steganography. The paper presents the results of solving such issues as the development of methods for obtaining DNA-based sequences, the evaluation of statistical and stochastic properties of such sequences, and the evaluation of similarity based on k-mer and MinHash distances. The results obtained indicate the prospects and relevance of further research in this area.

Time to separate from StackOverflow and match with ChatGPT for encryption

Cryptography is known as a challenging topic for developers. We studied StackOverflow posts to identify the problems that developers encounter when using Java Cryptography Architecture (JCA) for symmetric encryption. We investigated security risks that are disseminated in these posts, and we examined whether ChatGPT helps avoid cryptography issues. We found that developers frequently struggle with key and IV generations, as well as padding. Security is a top concern among developers, but security issues are pervasive in code snippets. ChatGPT can effectively aid developers when they engage with it properly. Nevertheless, it does not substitute human expertise, and developers should remain alert.

EFPB: Efficient Fair Payment Based on Blockchain for Outsourcing Services in Cloud Computing

Despite the maturity of cloud services (e.g., outsourcing of computational tasks), a number of operational challenges remain. For example, how do we ensure trust between outsourcers and workers in a zero-trust environment? While a number of blockchain-based solutions that eliminate the reliance on trusted third parties have been presented, many of these existing approaches do not achieve robust fairness and/or support compatibility with other systems. In this paper, we propose an efficient fair payment system using blockchain (EFPB), designed to achieve robust fairness and compatibility. Specifically, EFPB comprises a number of cryptographic building blocks, mainly: one-way accumulator (RSA-based construction), stealth address and symmetric encryption. We then evaluate the performance of EFPB to demonstrate that it is more efficient and low-cost than other competing schemes, as well as presenting a comparative summary of functionalities.

Study of Chaotic-based Audio Encryption Algorithms: A Review

Nowadays, multimedia communication has become very widespread and this requires it to be protected from attackers and transmitted securely for reliability. Encryption and decryption techniques are useful in providing effective security for speech signals to ensure that these signals are transmitted with secure data and prevent third parties or the public from reading private messages. Due to the rapid improvement in digital communications over the recent period up to the present, the security of voice data transmitted over various networks has been classified as a favored field of study in earlier years. The contributions to audio encryption are discussed in this review. This Comprehensive review mainly focuses on presenting several kinds of methods for audio encryption and decryption the analysis of these methods with their advantages and disadvantages have been investigated thoroughly. It will be classified into encryption based on traditional methods and encryption based on advanced chaotic systems. They are divided into two types, continuous-time system, and discrete-time system, and also classified based on the synchronization method and the implementation method. In the fields of information and communications security, system designers face many challenges in both cost, performance, and architecture design, Field Programmable gate arrays (FPGAs) provide an excellent balance between computational power and processing flexibility. In addition, encryption methods will be classified based on Chaos-based Pseudo Random Bit Generator, Fractional-order systems, and hybrid chaotic generator systems, which is an advantageous point for this review compared with previous ones. Audio algorithms are presented, discussed, and compared, highlighting important advantages and disadvantages. Audio signals have a large volume and a strong correlation between data samples. Therefore, if traditional cryptography systems are used to encrypt such huge data, they gain significant overhead. Standard symmetric encryption systems also have a small key-space, which makes them vulnerable to attacks. On the other hand, encryption by asymmetric algorithms is not ideal due to low processing speed and complexity. Therefore, great importance has been given to using chaotic theory to encode audio files. Therefore, when proposing an appropriate encryption method to ensure a high degree of security, the key space, which is the critical part of every encryption system, and the key sensitivity must be taken into account. The key sensitivity is related to the initial values and control variables of the chaotic system chosen as the audio encryption algorithm. In addition, the proposed algorithm should eliminate the problems of periodic windows, such as limited chaotic range and non-uniform distribution, and the quality of the recovered audio signal remains good, which confirms the convenience, reliability, and high security.

2F-MASK-VSS: Two-factor mutual authentication and session key agreement scheme for video surveillance system

The trend for deploying Video Surveillance Systems (VSSs) in public places has become common practice to maintain effective law and order in modern civilization. Further, data access control and the proper management of surveillance data with valid users are desirable for the safety and security of the communities. This paper aims to develop practical solutions to protect VSSs against evolving threats and challenges. This paper proposes a Two-Factor Mutual Authentication and Session Key Agreement usable in VSS (2F-MASK-VSS) environments for real-time data storage and access. In 2F-MASK-VSS, lightweight cryptographic tools, viz. hash function and symmetric key encryption, are used to maintain the desirable security features. In 2F-MASK-VSS, a surveillance camera captures real-time data and sends them securely to a central server for storage through the established session key agreement among valid concerns. Moreover, 2F-MASK-VSS can protect access control among valid users. The security strength of 2F-MASK-VSS has been proven by formal and informal analysis. The BAN logic model, AVISPA and Scyther tools validate the attack-resilience of 2F-MASK-VSS. Furthermore, the security analysis in the random oracle model shows that 2F-MASK-VSS is provably secure. In addition, 2F-MASK-VSS has been implemented using the Raspberry PI testbed to demonstrate its practical implementation.

Data encryption IS defined as a method of transforming information into a coded format, ensuring that only authorized individuals can successfully decode and comprehend the content. In addition, cryptography is principally categorized into two distinct types: symmetric key cryptography and asymmetric key cryptography. In this research, we conduct a comparative analysis of two cryptographic systems: RSA (asymmetric) and AES (symmetric key), specifically evaluating their performance in data encryption for point-to-point communications. The analysis focuses on the speed of file encryption and decryption as well as the length of the encrypted data. Experimental results reveal that both RSA and AES are robust encryption algorithms; however, AES outperforms RSA in terms of both encryption and decryption speeds while also producing a smaller remaining data size that could not be encrypted due. Finally, the paper has outlined strengths and weaknesses of reviewed algorithms which make it possible to effectively put these algorithms together in protecting information and satisfying the security needs of applications. Keywords: Encryption – Decryption– Cryptosystems– Encryption Algorithm- RSA– AES.

With the rapid development of Internet of Things (IoT) technology, Narrowband IoT (NB-IoT) has been widely adopted in smart cities, smart homes, and industrial automation due to its low power consumption, wide coverage, low cost, and high reliability. However, the associated security issues have become a critical factor hindering its further development. This paper aims to explore the security challenges in NB-IoT communication networks using encryption algorithms.

Initially, the paper reviews the fundamental principles and application scenarios of NB-IoT, analyzing the current challenges in network security, including data leakage, device tampering, and man-in-the-middle attacks. Subsequently, a security framework based on lightweight encryption algorithms is introduced, leveraging the strengths of both symmetric and asymmetric encryption to ensure security while reducing computational and communication overheads. Additionally, the application of blockchain technology in NB-IoT security is discussed, enhancing data credibility and system resilience against attacks through its decentralized nature. Theoretical derivations and simulation analyses confirm the effectiveness and feasibility of the proposed security framework. The results demonstrate that this framework significantly enhances the security performance of NB-IoT networks, providing theoretical support and practical guidance for the secure development of IoT.

Secure and efficient vehicle data downloading scheme with privacy-preserving in VANETs

Data downloading is a basic data transfer requirement in VANETs. Cooperation data downloading can use all V2C, V2I and V2V communications to improve the data downloading efficiency. Security and identity privacy preserving of data downloading should be paid more attention to protect the required vehicle. Otherwise, the data and identity information leakages would lead to immeasurable loss. To address these challenges, we propose a lattice-based secure vehicle data downloading scheme with privacy-preserving for VANETs. The vehicle request message authentication and identity privacy of the vehicle are achieved by a designed lattice-based ring signature. We prove that the proposed scheme is strong unforgeable and unconditional privacy preserving in the random oracle model. The request data also is encrypted by a symmetric encryption algorithm to achieve the data confidentiality. Moreover, thanks to the post-quantum security of the lattice-based cryptographic tools, the proposed data downloading also can defend against the quantum attacks. At the same time, cooperation data downloading also can be used in this paper to improve the effects of data downloading. Performance comparison and analysis shows that the proposed scheme shares some advantages with respect to the space and computation efficiency. The main character of the proposed scheme is that the impact of the vehicle ring group number on both the computation and space efficiency is effective controlled, such as the fixed signature length for any ring group size. As a result, the bandwidth and computation resources of VANETs can be saved by using the proposed scheme. We also simulate the proposed scheme by NS-3 which shows the average download success ratio is always within the interval [95%−100%] and cooperative downloading can improve the downloading efficiency by 86%.

Comparative Analysis of AES, Blowfish, Twofish, Salsa20, and ChaCha20 for Image Encryption

Nowadays, cybersecurity has grown into a more significant and difficult sci-entific issue. The recognition of threats and attacks meant for knowledge and safety on the internet is growing harder to detect. Since cybersecurity guar-antees the privacy and security of data sent via the Internet, it is essential, while also providing protection against malicious attacks. Encrypt has grown into an answer that has become an essential element of information security systems. To ensure the security of shared data, including text, images, or videos, it is essential to employ various methods and strategies. This study delves into the prevalent cryptographic methods and algorithms utilized for prevention and stream encryption, examining their encoding techniques such as advanced encryption standard (AES), Blowfish, Twofish, Salsa20, and ChaCha20. The primary objective of this research is to identify the optimal times and throughputs (speeds) for data encryption and decryption processes. The methodology of this study involved selecting five distinct types of images to compare the outcomes of the techniques evaluated in this research. The as-sessment focused on processing time and speed parameters, examining visual encoding and decoding using Java as the primary platform. A comparative analysis of several symmetric key ciphers was performed, focusing on handling large datasets. Despite this limitation, comparing different images helped evaluate the techniques' novelty. The results showed that ChaCha20 had the best average time for both encryption and decryption, being over 50% faster than some other algorithms. However, the Twofish algorithm had lower throughput during testing. The paper concludes with findings and suggestions for future improvements.

A Ciphertext Reduction Scheme for Garbling an S-Box in an AES Circuit with Minimal Online Time

The secure computation of symmetric encryption schemes using Yao’s garbled circuits, such as AES, allows two parties, where one holds a plaintext block m and the other holds a key k, to compute Enc(k,m) without leaking m and k to one another. Due to its wide application prospects, secure AES computation has received much attention. However, the evaluation of AES circuits using Yao’s garbled circuits incurs substantial communication overhead. To further improve its efficiency, this paper, upon observing the special structures of AES circuits and the symmetries of an S-box, proposes a novel ciphertext reduction scheme for garbling an S-box in the last SubBytes step. Unlike the idea of traditional Yao’s garbled circuits, where the circuit generator uses the input wire labels to encrypt the corresponding output wire labels, our garbling scheme uses the input wire labels of an S-box to encrypt the corresponding “flip bit strings”. This approach leads to a significant performance improvement in our garbling scheme, which necessitates only 28 ciphertexts to garble an S-box and a single invocation of a cryptographic primitive for decryption compared to the best result in previous work that requires 8×28 ciphertexts to garble an S-box and multiple invocations of a cryptographic primitive for decryption. Crucially, the proposed scheme provides a new idea to improve the performance of Yao’s garbled circuits. We analyze the security of the proposed scheme in the semi-honest model and experimentally verify its efficiency.

Hybrid cryptography-based scheme with conditional privacy-preserving authentication and memory-based DOS resilience in V2X

To secure Vehicle-to-everything (V2X) communications, many Conditional Privacy-Preserving Authentication schemes (CPPA) use symmetric and asymmetric encryption during the authentication process. However, several existing schemes have some security limitations regarding VANET requirements. In many symmetric cryptography-based schemes, the participants are required to share the same keys which could compromise the security of the network in case the key of one participant is compromised, while many asymmetric cryptography-based schemes take much time during the authentication process, and don't address the denial-of-service attack. In this paper, we propose a certificateless scheme that does not require a certificate and prevents the escrow problem. Plus, it uses the elliptic curve cryptography and avoids bilinear pairing and Map-to-Hash functions. We call our scheme Hybrid Cryptography-Based Scheme with a Conditional Privacy-Preserving Authentication (HCBS-CPPA), as it uses both symmetric and asymmetric cryptography during the authentication process. Our scheme combines the strength of an asymmetric encryption that satisfies non-repudiation, and the strength of a symmetric encryption that allows to perform a lightweight authentication. In addition, we show that our scheme is resilient to memory-based Denial of Service (DOS) attack which occurs when an attacker floods the memory of a receiver with invalid messages. A security proof shows that HCBS-CPPA is secure in the random oracle. Regarding the simulation of our scheme, it turns out that HCBS-CPPA has the best performance when compared with several existing certificateless schemes. Additionally, it requires less execution time during the signing and verification process, as well as less communication overhead when compared to the existing schemes.

Enhancing Cryptographic Primitives through Dynamic Cost Function Optimization in Heuristic Search

The efficiency of heuristic search algorithms is a critical factor in the realm of cryptographic primitive construction, particularly in the generation of highly nonlinear bijective permutations, known as substitution boxes (S-boxes). The vast search space of 256! (256 factorial) permutations for 8-bit sequences poses a significant challenge in isolating S-boxes with optimal nonlinearity, a crucial property for enhancing the resilience of symmetric ciphers against cryptanalytic attacks. Existing approaches to this problem suffer from high computational costs and limited success rates, necessitating the development of more efficient and effective methods. This study introduces a novel approach that addresses these limitations by dynamically adjusting the cost function parameters within the hill-climbing heuristic search algorithm. By incorporating principles from dynamic programming, our methodology leverages feedback from previous iterations to adaptively refine the search trajectory, leading to a significant reduction in the number of iterations required to converge on optimal solutions. Through extensive comparative analyses with state-of-the-art techniques, we demonstrate that our approach achieves a remarkable 100% success rate in locating 8-bit bijective S-boxes with maximal nonlinearity, while requiring only 50,000 iterations on average—a substantial improvement over existing methods. The proposed dynamic parameter adaptation mechanism not only enhances the computational efficiency of the search process, but also showcases the potential for interdisciplinary collaboration between the fields of heuristic optimization and cryptography. The practical implications of our findings are significant, as the ability to efficiently generate highly nonlinear S-boxes directly contributes to the development of more secure and robust symmetric encryption systems. Furthermore, the dynamic parameter adaptation concept introduced in this study opens up new avenues for future research in the broader context of heuristic optimization and its applications across various domains.
