A Usable Encryption Solution for File-Based Geospatial Data within a Database File System

Developing a security solution for spatial files within today’s enterprise Geographical Information System (GIS) that is also usable presents a multifaceted challenge. These files exist in “data silos” of different file server types, resulting in limited collaboration and increased vulnerability. While cloud-based data storage offers many benefits, the associated security concerns have limited its uptake in GIS, making it crucial to explore comparable alternative security solutions that can be deployed on-premise and are also usable. This paper introduces a reasonably usable security solution for spatial files within collaborative enterprise GIS. We explore a Database File System (DBFS) as a potential repository to consolidate and manage spatial files based on its enterprise document management capabilities and security features inherited from the underlying legacy DBMS. These files are protected using the Advanced Encryption Standard (AES) algorithm with practical encryption times of 8 MB per second. The final part focuses on an automated encryption solution with schemes for single- and multi-user files that is compatible with various GIS programs and protocol services. Usability testing is carried out to assess the solution’s usability and focuses on effectiveness, efficiency, and user satisfaction, with the results demonstrating its usability based on the minimal changes it makes to how users work in a collaborative enterprise GIS environment. The solution furnishes a viable means for consolidating and protecting spatial files with various formats at the storage layer within enterprise GIS.

Multi-Image Steganography

Steganography is the practice of concealing information within various types of data, encompassing the embedding of confidential content like messages, images, audio, or video within a cover image. The primary objective involves hiding the secret message or image within the selected image through the utilization of the Least Significant Bit (LSB) technique. To ensure the safeguarding and security of the concealed content, the Advanced Encryption Standard (AES) Algorithm is implemented. The comparison of different image formats, each varying in text length or image size, is conducted. The algorithm's efficacy is evaluated through metrics such as Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE), with a higher PSNR value indicating a superior image quality. Steganography assumes a vital role in numerous applications, including but not limited to medical, military, One Time Password (OTP), and copyright protection.

Towards improving the security of wireless networks using secured session keys

ABSTRACT Wireless Networks are mostly based on the IEEE 802.11 standards and with so many applications being wireless, without proper security, sensitive information may be at risk. Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA) are two of the most commonly used mechanisms for implementing security in wireless networks. However, research has shown that both of these can be cracked quite easily within a short period as these mechanisms use a key-based security implementation for performing operations. The key can be found by capturing a few packets and hence security is compromised. In this study, the solution that is proposed by generating a secured session key using the Advanced Encryption Standard (AES) algorithm, which is valid only for a specific session and cannot be cracked easily by the intruder, and hence will not affect the security of the entire network. The key exchange is made by the Diffie-Hellman key exchange protocol. The proposed solution was implemented over a network and found to be secure.

Privacy is given top priority as far as communication involving transfer of confidential document or data is concerned. There is therefore a need to keep confidential data secretive from being invaded by unauthorised access, and this is done through cryptography algorithms, where the Advanced Encryption Standard algorithm has been the widely accepted symmetric block encryption algorithm for such purposes. This paper therefore focuses on developing a new AES-512 bits symmetric encryption algorithm through modification of the conventional AES-128 algorithm to be used purposefully in the classroom for document transfer.The development comes with increasing the plaintext bits of the conventional AES-128 algorithm to 512 bits plaintext which undergoes five operational transformations: STATE, SKGF, SRL, SCL and AARC through key size in the Galois field, GF(29). A numerical example is then given to explain the use of the algorithm, and finally, we provide a comparative study of this algorithm and other existing symmetric encryption models, such as the AES-128 and DES algorithms.

The spectacular growth of computational clouds has drawn attention and enabled intensive computing on client devices with constrained resources. Smart phones mostly use the data centre demand service model to provide data to computationally intensive applications. It is challenging to outsource sensitive and private information to distant data centres due to growing concerns about data privacy and security. Therefore, conventional security algorithms have to be upgraded to address the brand-new security concerns that have emerged in the cloud environment. The Advanced Encryption Standard (AES) algorithm encrypts and decrypts messages using the four steps, namely Sub-Bytes, Shift-Rows, Mix-Columns, and Add Round Key. It has been changed so that the Sub-byte transformation depends on the round key. Making the S box round key dependent is intended to make it such that even a little change in the key will have a big impact on the cipher text. The avalanche effect and execution time of the standard and modified AES algorithms are implemented and assessed.  In order to suggest a safe and efficient solution, the study also aims to modify the shift rows and the mix column phases of AES. Using cryptographic techniques such as elliptic curve cryptography (ECC), several protocols and algorithms have been developed to guarantee the security and integrity of the data. The proposed solution combines the enhanced and updated The Advanced Encryption Standard (AES) technology with the ECC to guarantee data secrecy.  The avalanche effect approach is used in this study to explore and analyze the strength and quality of the new s-box. The results demonstrated that each encryption operation generates a unique cipher text. A strong avalanche effect was also achieved with the redesigned dynamic s-box using irreducible polynomials, surpassing the strict avalanche criterion (SAC). The results show that the proposed method ECC-EAESKDS Elliptic Curve Cryptography-Enhanced AES with Key Dependent S box is efficient and yields better results than the alternatives. According to the suggested security architecture, cloud users may control data protection and integrity in a secure manner.

Abstract Software-defined networking offers a flexible and programmatically efficient network design. Security in today’s ad hoc mobile wireless network is paramount and incredibly challenging. Software-defined network is used to automatically and dynamically manage and control large network devices, network services, traffic paths, network topology, and packet management (quality of service). Recently different attackers are attacking our data when forwarding from one device to another. Therefore, software-defined networking and a Hybrid Rivest, Shamir, and Adelman (RSA)–Advanced Encryption Standard (AES) cryptography algorithm are needed to establish the concept of software-defined networking in mobile ad hoc networks to improve security and routing efficiency. The proposed Hybrid Cryptography Algorithm (HCA)-Based SDN mainly creates strong detection, prevention, and authentication mechanisms for MANET. The proposed secure data channel throughput increased by 0.4%, and the suggested system latency was 3.6% lower than the Normal MANET. It is already proved that the Hybrid cryptography algorithm also generates a key for security faster than RSA (Rivest, Shamir, and Adelman). The performance of the RSA–AES (hybrid) approach for encrypting and decrypting broad data significantly beats the RSA-Blowfish algorithm. In decrypting files, the hybrid approach (RSA–AES) outperforms the RSA-Blowfish method 11.2 times more efficiently when the file size is 32 kB; however, efficiency is increased by 77.1 times when the file size exceeds 4,096 kB. The experimental result shows that as the file size increases the hybrid RSA–AES solution outperforms RSA when the file is only 145 bytes; however, when the file is 6,460 bytes in size, the efficiency is multiplied by 61.3. As file size increases, RSA is less efficient than the hybrid encryption method. This is more preferred to be implemented for different parts of wireless networks like MANET.

Now-a-days, healthcare monitoring system is very much important system in the medical field to know the patient‘s health status immediately. In the proposed system, the sensors are fixed over the patient’s body or placed at some distances around the body to collect patient’s significant parameters like blood pressure, temperature, heart beat rate, etc. These parameters are collected by the healthcare professionals through some connectivity mechanisms like Bluetooth, ZigBee, etc. These significant data will be outsourced to the cloud storage in a secure way to avoid attack from the attackers. So, we need some protection mechanism to safeguard this information. This article proposes a light weight cryptographic algorithm (symmetric key) via random number key generation using Diffie-Hellman key exchange based on Elliptic Curve (ECDH) cryptography. As a result of substituting bytes (S-box) and folding (horizontal and vertical) operations, the proposed symmetric key algorithm achieves the foremost properties of cryptography such as confusion and diffusion quite well.

Secure and Efficient NVM Usage for Embedded Systems Using AES-128 and Huffman Compression

Embedded systems are customized systems designed to meet functionality and specific usage purposes. These systems often grapple with challenges such as power interruptions, limited memory space, and the expectation of a long operational lifespan. It is in this context that Non-Volatile Memory (NVM) plays a vital role. NVM is a type of memory that ensures data persistence even in situations of temporary power loss or signal interruptions. Efficiently utilizing NVM is a critical necessity for the effectiveness and reliability of these systems. Efficient utilization of NVM necessitates the effective management of write and read cycles. Previous studies have demonstrated the efficient utilization of NVM sectors by ensuring that no garbage bytes remain unallocated. Previous studies have demonstrated the efficient utilization of NVM by compressing the data to be written into NVM using the Huffman compression algorithm, and filling sectors without any residual garbage bytes. This paper aspires to advance beyond prior research by integrating the Advanced Encryption Standard (AES-128) block encryption algorithm, aiming to optimize the utilization of NVM to a greater extent. The AES-128 algorithm provides data security with encryption and decryption operations. By applying AES-128 encryption to the data before writing it to the NVM, this work adds a data security layer to the developed software module. Data is divided into blocks using this algorithm. Each block is encrypted independently and then reassembled. The encryption process includes key management, substitution-permutation network layers, and multiple rounds, all of which make substantial contributions to high-level data security. The resulting encrypted data is compressed using the Huffman compression algorithm. This process enhances both the security and efficiency of data storage. The data is written to NVM with maximum efficiency, ensuring that no residual garbage bytes remain, upon the completion of the encryption and compression processes. This study surpasses previous research by enhancing storage security and efficiency through these processes. Moreover, the developed secure and efficient NVM usage, as it fills the NVM with data without leaving any garbage bytes, results in slower processing speed compared to standard NVM usage. Therefore, in future research, interventions with code optimization techniques can be applied to the developed algorithms to enhance write and read speeds.
