According to the results of the second stage of the international competition for research and development of standards for asymmetric cryptographic transformations of the post-quantum period, the Rainbow electronic signature (ES) mechanism received a positive assessment and recognition as a finalist. Its important advantages over other post-quantum ESs consist in less complexity of direct and inverse transformations, i.e., signature generation and verification, as well as significantly reduced signature length. At the same time, the length of its public key is quite large. Therefore, it is thought that Rainbow is not suitable as a general-purpose ES algorithm to replace the algorithms currently defined in FIPS 186-4. In particular, large public keys make certificate chains extremely large. However, there are applications that do not need to send keys too often, so this disadvantage in these cases may be insignificant. Under these conditions, the Rainbow ES mechanism can find application, including that one increasing the diversity of postquantum ESs. Also, it is significantly problematic to limit the security levels of Rainbow ES 256 bits against classical and 128 bits against quantum cryptanalysis. The subject of this article is the analysis and generalization of designs of the Oil-Vinegar public key authentication systems mechanism based on the Rainbow ES use. This is an important direction in creating secure and efficient authentication systems for practical applications using public keys, such as inexpensive smart cards, when speed is required in the production and verification of ES. A feature of such authentication mechanism is the implementation of the idea of a multilevel Oil-Vinegar system. It is believed that the ES-based authentication system should be more secure in terms of cryptographic stability and more efficient in terms of widespread use in low-power, etc. applications. The importance of solving this problem lies in the potential use of the Rainbow mechanism as a secure and highly efficient public-key authentication system based on ES.

Main Disadvantage

The paper considers the description of electronic signature scheme Rainbow, which is based on multivariate transformations. It is a generalization of the UOV structure, which provides efficient parameterization due to the additional algebraic structure. The article provides an initial analysis of known attacks on the ES Rainbow scheme. Also, algorithms for generating general system parameters for 384 and 512 security bits were developed and the results are presented in this paper. The study found that the Rainbow signature generation process consists of simple operations of linear algebra, such as multiplying matrix vectors and solving linear systems over small finite fields. Another advantage of Rainbow is that this scheme offers very small signatures of only a few hundred bits. But the main disadvantage of Rainbow is the large size of public keys.

Encryption And Decryption

In this paper two methods are used, namely the vigenere cipher method and the RSA method. The vigenere cipher method is an example of a symmetric algorithm, while RSA is an example of an asymmetric algorithm. The combination of these two methods is called hybrid cryptography which has the advantage in terms of speed during the encryption process. Each process, which is encryption and decryption, is carried out twice, so that security can be ensured. In the process of forming the key used the RSA method. In the encryption process using public keys that have been generated before when the key is formed. This public key is used in sending data to the recipient of a secret message where this key is used for the data encryption process. The Secret key is kept and will be used during the decryption process. There is a system architecture that describes how clients and servers communicate with each other over the internet using the TCP protocol where the client here is an IoT device and the server is a server.

The use of public key algorithms to sensor networks brings all merits of these algorithms to such networks: nodes do not need to encounter each other in advance in order to be able to communicate securely. However, this will not be possible unless “good” key management primitives that guarantee the functionality of these algorithms in the wireless sensor networks are provided. Among these primitives is public key authentication: before sensor nodes can use public keys of other nodes in the network to encrypt traffic to them, they need to make sure that the key provided for a particular node is authentic. In the near past, several researchers have addressed the problem and proposed solutions for it as well. In this chapter we review these solutions. We further discuss a new scheme which uses collaboration among sensor nodes for public key authentication. Unlike the existing solutions for public key authentication in sensor network, which demand a fixed, yet high amount of resources, the discussed work is dynamic; it meets a desirable security requirement at a given overhead constraints that need to be provided. It is scalable where the accuracy of the authentication and level of security are merely dependent upon the desirable level of resource consumption that the network operator wants to put into the authentication operation.

Malware causes damage by stealing confidential data or making other software unusable. Ensuring software trustworthiness is difficult because malware may disguise itself to appear benign or trusted. This chapter explores the problem of making software more trustworthy through the use of binary integrity mechanisms. The authors review the problem of devising an effective binary integrity protection, and discuss how it complements other operating system security measures. They analyze design factors for binary integrity and compare existing systems. The authors then present a prototype which exemplifies a mandatory binary integrity mechanism and its integration within an operating system. Their system, BinAuth, demonstrates a practical, lightweight in-kernel binary authentication system for Microsoft Windows. A system like BinAuth shows that mandatory authentication is practical on complex commodity operating system like Windows. To deal with various constraints in the user’s environments, BinAuth uses a flexible scheme which does not mandate public key infrastructure (PKI) although it can take advantage of it. The authors also combine the authentication with a simple software-ID scheme which is useful for software management and vulnerability assessment.

Purpose The purpose of the study is to develop a secure, efficient, and enhanced user authentication mechanism to achieve reliable and authenticated connection. In online transactions, users and resources are located at different places, and the sensitive information is to be protected and transferred using the suitable, reliable mechanism. Design/methodology/approach One of the latest approach to handle the requirement is by a Public Key Infrastructure (PKI) or its variant Wireless Public Key Infrastructure (WPKI). Fundamental management techniques are required to be very secure and vital since they are one of the points of attack in public key cryptosystem. Entity authentication and key agreement (AKA) is a critical cryptographic problem in wireless communication, where a mutual entity authentication plays a vital role in the establishment of the secure and authentic connection. This paper proposes an efficient and enhanced AKA scheme (EAKA) with the end-to-end security and verifies the proposed system for protection using automated validation of internet security protocols and applications. An efficient way for the implementation of an enhanced version of the protocol is proposed using a lattice-based cryptographic algorithm. Findings The time consumed for the proposed research work shows that it is practical and acceptable. Originality/value The proposed research work is an efficient and enhanced user authentication mechanism.

Nowadays, a wide variety of computer systems use authentication protocols based on several factors in order to enhance security. In this work, the viability of a second-phase authentication scheme based on users’ mouse behavior is analyzed by means of classical Artificial Intelligence techniques, such as the Support Vector Machines or Multi-Layer Perceptrons. Such methods were found to perform particularly well, demonstrating the feasibility of mouse behavior analytics as a second-phase authentication mechanism. In addition, in the current stage of the experiments, the classification techniques were found to be very stable for the extracted features.

Carbon, aramid and glass fibers are inherently superior to conventional textile fibers in terms of mechanical properties as well as other chemical characteristics. Because of inherent advantages and disadvantages associated with each material, it is generally better to hybridize them to fully benefit of their high performance in many practical applications. In this paper, the possibility of hybridizing Carbon/Aramid-, Carbon/Glass- and Aramid/Glass- matrices has been investigated through the commingling process. In the experiment, several process parameters were selected and they include pressure, yarn oversupply-rate and different nozzle types. As a result of experiments, it was concluded that the hybridized materials has shown better performance than individual reinforced filament yarns in terms of mechanical properties. For small tensile forces, the Carbon/Glass/matrix combination turned out to be good enough for general purpose applications. However, for high tensile applications, Carbon/Aramid or Aramid/Glass with matrix combinations was better than the other material combinations. The hybridization process was also investigated under an air pressure of 5 bar, a yarn oversupply-rate of 1.5% for reinforced filaments, and 3.5% to 6% for matrix materials, respectively. It was also shown from the experimental results that Carbon/Glass/matrix combination may be desirable for small tensile force applications and Carbon/Aramid/matrix and Glass/Aramid/matrix combinations most suitable for heavy tensile force applications, respectively. As a matrix material, polypropylene and polyester have shown better performance than polyether-ether-keeton in terms of tensile property.
