State of development, research and standardization of cryptographic transformations such as asymmetric encryption and post-quantum key encapsulation protocol

Abstract

The paper presents the state of development of cryptocurrencies such as ACS and PIC at the international and national levels. The state of standardization of cryptocurrencies of ASS and PIK at the international competition NIST of the USA, the requirements put forward to candidates on 2 and 3 rounds of competition are considered. The state of standardization of crypto transformations of this type at the national level in Ukraine is considered, and a brief description of the national standard ASSH DSTU 8961: 2019, based on algebraic lattices, is given. The methodology and results of achieving the national standard DSTU 8961:2019 against attacks by third-party channels in terms of the dependence of the time of direct and reverse transformation (encapsulation and decapsulation of the key) on the number of units in the private key.
