1.3
draft-smyshlyaev-tls13-gost-suites-02
Abstract
The purpose of this document is to make the Russian cryptographic
standards available to the Internet community for their
implementation in the Transport Layer Security (TLS) Protocol Version
1.3.
This specification defines four new cipher suites and seven new
signature schemes based on GOST R 34.12-2015, GOST R 34.11-2012 and
GOST R 34.10-2012 algorithms.
