An improved public key infrastructure-based digital signature authentication service for higher key storage system

In general, we quickly forget about boxes with paper archives, and there is not even a single sheet of paper on the desktop. If a paper document is sent to the institution through regular mail, the artifact is immediately scanned and digitized. In fact, it turned out to be quite the opposite. The more a company uses computers for digital workflows, the more it documents and prints. Above all, every document must be authenticated. A document without a signature is only a draft or an information note. To get the signature, the documents are printed and then often scanned, and the original documents are kept on file. It is now clear that the (paperless) workflow cannot be implemented without electronic digital signatures. In this study, an improved public key infrastructure-based Digital Signature Authentication Service is proposed for higher key storage system. In this method, the CAs included in the list provide certificate-based digital identifiers and time stamping services that comply with global regulations, such as the eIDAS standard. Electronic digital signatures are already supported for most popular office document formats. Timestamps are supported, including multi-person document signatures.

Multi-Layer Digital Validation of Candidate Service Appointment with Digital Signature and Bio-Metric Authentication Approach

Proposed work promotes a unique data security protocol for validating candidate’s service appointment. Process initiated with concealment of private share within the first segment of each region of the e-letter at commission’s server. This is governed by hash operations determining circular orientation of private share fragments and their hosted matrix intervals. Signed e-letter downloaded at the posted place is validated through same hash operations and public share. Candidate’s on spot taken fingerprint are concealed in two segments for each region of the eletter adopting similar hiding strategies. The copyright signature of posting place is similarly shielded on fourth segment of each region using hash operations. The certified e-letter is thoroughly validated at commission’s server and signatures stored justify authenticity of appointment and proper candidature at the posting place. The superior test results from wider angles establishes the efficacy of the proposed protocol over the existing approaches.

Efficient Key Management Mechanism with Trusted Gateways for Wireless Mesh Networks

Securing wireless mesh networks (WMNs) is a crucial issue due to its intrinsic characteristics. Several endangered features might emerge due to the exposure of the networks to a diversity of medium access control (MAC) layers such as distributed denial of service (DDoS) attacks, false reply attacks, and other identity attacks. Against these attacks, the determination of existing techniques is insufficient to ensure the complete security solutions to protect the backbone network at multiple levels. As a result, effective, scalable, and integrated security solutions for WMNs are required. In WMNs, protecting legitimate gateway nodes and internal mesh routers against malicious attacks at the MAC layer remains a difficult problem. Our proposed trust-based security mechanism includes distributed authentication and deauthentication algorithms that validates backbone mesh routers as well as gateway nodes. Particularly, this proposed model targets DDoS attacks in the network. The proposed DDoS attack prevention mechanism (DAPM) uses distributed authentication and deauthentication algorithms to build trusted group heads for managing secure data communication in the network. Our research and practical results show that the proposed mechanism decreases the severity of malicious nodes and strengthens the security compared to existing centralized schemes such as digital signature authentication (DSA-Mesh, MENSA, Mobisec, and AHKM). The experimental solutions show the significance of the proposed work with 10% to 12% of better performance than the existing techniques.

The method realizes digital signature and ensures the confidentiality of the transmitted data. Finally, this paper proposes a concrete digital signature experiment system implemented in Java. The results of this study show that the computer vision signature encryption system helps to improve the reliability of the system.

Secure Authenticated Communication Via Digital Signature and Clear List in VANETs

Vehicular ad hoc network (VANET) plays a vital role in the intelligent transportation system (ITS). When a vehicle receives a message through network, the CRL (certificate revocation list) checking process will operate before certificate and signature verification. After successful authentication, a CRL list is created based on authentication. This CRL is used to verify whether a vehicle node can be permitted for communication in the VANET network. But when using CRL, a huge amount of storage space and checking time is needed. So we proposed a method without the CRL list. It mentions a key management list to overcome large storage space and checking time. Even it reduced the access delay. For access permission we can do an authentication system based digital novel signature authentication (DNSA) for each vehicle in the VANET with the RSU unit or with other participant node vehicles in the communication as per the topology. We can perform an efficient and secured communication in VANET.

Improving security against cache memory attacks for dual field multiplier design based on elliptic curve cryptography

The elliptic curve cryptographic (ECC) technique is employed for various security standards like security key management, digital signature and data authentication. The ECC technique is capable of undertaking sequential and equivalent mode processes through the unified design that is used equally for binary field and in the leading area of cryptosystems. Furthermore, a progressive transposition method and control information route are combined with the ECC mainframe, which offers efficient throughput, and adaptive calculation with low power. The dual-field Montgomery multiplier-carry save adder (DMM-CSA) structure is designed for the ECC system. The DMM structure has been developed using CSA in this method. The adder requires more number of Full Adders for the circuit design, which has occupied more area. To overcome this problem, this work introduces the dual field Vedic multiplier-look up table carry select adder (DVM-LCSLA) which is used to increase the performance of the ECC scheme for 256 bit. The first aim of the methods mentioned above is to develop a high-performance modular inversion for the ECC technique by employing application specified integrated chip and field programmable gate array (FPGA) implementation with the help of Verilog code. FPGA results indicate the analysis of power utilization, time delay information and Hardware area overhead in DVM-LCSLA used in ECC system compared to the state-of-art methods.

Trust Management Scheme Based on Hybrid Cryptography for Secure Communications in VANETs

Vehicular Ad hoc Networks (VANETs) are used to improve traffic management and reduce the number of road accidents by providing safety applications. However, VANETs are susceptible to a number of security attacks from malicious entities. To secure the network against these attacks, most of the researchers have proposed various security schemes based on cryptography and trust management. While both cryptography and trust management are effective to some extent, each scheme has some flaw to fully secure the network. In this paper, we propose a trust management scheme based on hybrid cryptography (TMHC) to secure VANET to a larger extent. As authentication is an integral part of trust establishment and secure communications between vehicles, the proposed TMHC integrates hybrid cryptography based authentication for efficient and robust trust management scheme. The hybrid cryptography includes, asymmetric identity-based (ID-based) digital signature and symmetric hash message authentication code (HMAC). The trusted road-side unit (RSU) evaluates trust-value, whereas, agent trusted authority (ATA) computes trust-value of vehicle based on its reward-points. The results are gained with extensive simulations to validate the proposed scheme. The results show that the proposed scheme meets security requirements and performs effectively. The communication overhead, computation overhead, storage overhead, and end-to-end delay of the proposed scheme were improved by 6% to 15%, 9% to 23%, 7% to 19%, and 4% to 15.85%, respectively, as compared to existing schemes.

A key management scheme realising location privacy protection for heterogeneous wireless sensor networks

Key management is the core of wireless sensor network (WSN) security management technology. At present, the protection of the source location information of nodes has also received great attention. In this paper, we combine identity-based encryption (IBE) algorithm with elliptic curve cryptography (ECC) based digital signature authentication to achieve more secure authentication. Then we use the double encryption method to realise the location privacy protection. Finally, we adopt a new routing update scheme to prevent attackers from initiating sinkhole attacks. In addition, we add timestamps to messages transmitted between nodes to defend against resend attacks. The scheme we proposed occupies a small amount of key storage space, consumes relatively more energy to protect the location information of nodes in the heterogeneous sensor network (HSN), and prevents attackers from initiating sinkhole attacks and resend attacks, thereby enhancing network security.

IDsMA: An integrated digital signature and mutual authentication mechanism for securing the cognitive radio networks

SummaryEnabling a reliable and secure communication in cognitive radio networks (CRNs) is one of the interesting and demanding research areas and these days, it is used in wide range of applications. The traditional works mainly aimed to improve the spectrum efficiency and bandwidth utilization of the CRN. Moreover, it focused on attack detection in the network for improving the reliability. Thus, this work intended to secure the CRN by considering the objectives of both attack detection and quality of service (QoS) improvement. For this purpose, an integrated digital signature and mutual authentication (IDsMA) mechanism is proposed in this paper, which incorporates the benefits of both security and reliability. Also, the Rivest‐Sharmir‐Adlemann (RSA) algorithm is utilized to encrypt and decrypt the data at the transmitter and receiver side. Here, the unique user ID is generated by the service eNodeB based on the hash function, which is validated at the server side for validating the authenticity of the user. Furthermore, the particle swarm optimization (PSO) and relevant vector machine (RVM) techniques are utilized for optimal channel selection and attack classification. The simulation results evaluate the performance of the proposed technique by using various performance measures. Also, its superiority is proved by comparing the proposed technique with the existing techniques.

HCAHF: A New Family of CA-based Hash Functions

Cryptographic hash functions (CHF) represent a core cryptographic primitive. They have application in digital signature and message authentication protocols. Their main building block are Boolean functions. Those functions provide pseudo-randomness and sensitivity to the input. They also help prevent and lower the risk of attacks targeted at CHF. Cellular automata (CA) are a class of Boolean functions that exhibit good cryptographic properties and display a chaotic behavior. In this article, a new hash function based on CA is proposed. A description of the algorithm and the security measures to increase the robustness of the construction are presented. A security analysis against generic and dedicated attacks is included. It shows that the hashing algorithm has good security features and meet the security requirements of a good hashing scheme. The results of the tests and the properties of the CA used demonstrate the good statistical and cryptographic properties of the hash function.

A Network Topology Control and Identity Authentication Protocol with Support for Movable Sensor Nodes.

It is expected that in the near future wireless sensor network (WSNs) will be more widely used in the mobile environment, in applications such as Autonomous Underwater Vehicles (AUVs) for marine monitoring and mobile robots for environmental investigation. The sensor nodes’ mobility can easily cause changes to the structure of a network topology, and lead to the decline in the amount of transmitted data, excessive energy consumption, and lack of security. To solve these problems, a kind of efficient Topology Control algorithm for node Mobility (TCM) is proposed. In the topology construction stage, an efficient clustering algorithm is adopted, which supports sensor node movement. It can ensure the balance of clustering, and reduce the energy consumption. In the topology maintenance stage, the digital signature authentication based on Error Correction Code (ECC) and the communication mechanism of soft handover are adopted. After verifying the legal identity of the mobile nodes, secure communications can be established, and this can increase the amount of data transmitted. Compared to some existing schemes, the proposed scheme has significant advantages regarding network topology stability, amounts of data transferred, lifetime and safety performance of the network.

The basic idea is to use two-way digital signature authentication information, and in the process of message transmission, to use negotiated session key and asymmetric encryption technology to encrypt messages.

CPK-based login authentication for electricity operation information system

Login authentication security is indispensable to applications of client/server (C/S) structure. Although some security technology in login authentication is relatively mature after years of development, it cannot meet high security requirements for the system in the case of limited resources. To deal with it, this paper proposes a new login authentication solution and applies it in electricity operation information system (EOIS), an application aiming at electrical equipment overhaul and report. The authors firstly discuss the reason why combined public key (CPK) is adopted as the key technology instead of the common one public key infrastructure (PKI). Secondly, they expatiate on CPK generation mechanism and the realizing process of login authentication, including local authentication using CPK-based digital signature and remote authentication using web service. Then, some results from three encryption methods (message-digest algorithm 5(MD5), secure hash algorithm (SHA-1) and CPK-based digital signature) to test EOIS are given, which show that the new solution builds its security on Hash function chosen and protection of combined private key. Finally, the security analysis reveals that CPK-based login authentication is safer to ensure the certainty of user identity, the integrality and non-repudiation of messages, and the confidentiality of transmission.
