Working with cryptographic key information

Abstract

It is important to create a cryptographic system such that the encryption system does not depend on the secret storage of the algorithm that is part of it, but only on the private key that is kept secret. In practice, key management is a separate area of cryptography, which is considered a problematic area. This paper describes the main characteristics of working with cryptographic key information. In that, the formation of keys and working with cryptographic key information are stored on external media. The random-number generator for generating random numbers used for cryptographic key generation is elucidated. To initialize the sensor, a source of external entropy, mechanism “Electronic Roulette” (biological random number), is used. The generated random bits were checked on the basis of National Institute of Standards and Technology (NIST) statistical tests. As a result of the survey, the sequence of random bits was obtained from the tests at a value of P≥0.01. The value of P is between 0 and 1, and the closer the value of P is to 1, the more random the sequence of bits is generated. This means that random bits that are generated based on the proposed algorithm can be used in cryptography to generate crypto-resistant keys.

Building Applications and Developing Digital Signature Devices based on the Falcon Post-Quantum Digital Signature Scheme

“…Table I details the survey, analysis, and performance evaluation in terms of speed, outputs, and compatibility with the NTRU lattice. In the implementation of the algorithm presented in [5], matrix B is taken as a trapdoor and then the algorithm generates vector s with normalized form ∥B∥ GS . The process of generating a short vector s increases the security of the algorithm.…”

“…With the emergence of quantum computers, traditional cryptography is gradually losing its security elements, and becomes a threat to the security of asymmetric cryptosystems and digital signatures based on number theory in quantum computers, such as RSA, DSA, Diffie-Hellman, ElGamal, and elliptic curve variants [1][2][3][4]. Post-quantum cryptosystems must ensure their security properties even in the face of quantum computers [4][5]. The Falcon scheme is one of the post-quantum digital signature schemes nominated in the postquantum cryptography competition that can be used on NIST quantum computer systems as of 2017 [1].…”

Wireless channel-based ciphering key generation: effect of aging and treatment

“…However, this portion requires gigantic efforts to have the wireless transmission secured. This issue has become significant after the ever-increasing amount of data transmitted, wirelessly [1]- [3]. Since electromagnetic waves can propagate anywhere, data transmission is fundamentally fraught with danger.…”
