The development of quantum computers poses a new security threat to network
infrastructures and services, as they will be powerful enough to break the most common …

Due to the fundamentally different approach underlying quantum cryptography (QC), it has
not only become competitive, but also has significant advantages over traditional …

This work presents the main results of development of a new keystream generator, which is
named “Strumok”, and offered as a candidate for the national symmetric encryption standard …

This article is devoted to the analysis of possibilities of implementation of digital signature
schemes based on using error-correcting codes. This approach allows cryptographers to …

Methods for implementing integer arithmetic operations of addition, subtraction, and
multiplication in the system of residual classes are considered. It is shown that their practical …

Blockchain is a new class of technology in computer science that combines cryptography
and distributed computing. It provides a digitally timestamped database where the network …

In this paper we consider Code-Based Public-Key Cryptosystems (McElice and Niederreiter
schemes). These mechanisms provide high speed conversion and cryptographically strong …

Blockchain technology is currently one of the most popular topics in the field of information
technology. Blockchain is often associated with cryptocurrency or electronic cash, but it can …

The existing public key infrastructure main development principles are given. Problems
related to the functioning of such system are described. The opportunity to secure use an …

In this paper we research code-based electronic digital signature schemes, which ware
submitted to the contest of post-quantum crypto algorithms NIST PQC. There are explored …
