Abstract

   The usage of cryptographic algorithms defined by GOST R 34.10-2012
   [GOST3410-2012] and GOST R 34.11-2012 [GOST3411-2012] standards for
   protection of the information is carried out, as a rule, within the
   cryptographic protocols based on the accompanying algorithms.

   This memo contains a description of the accompanying algorithms.  It
   defines the pseudorandom functions, the key agreement protocols based
   on the Diffie-Hellman method, the parameters of elliptic curves, the
   key derivation functions and the algorithms used for export of keying
   material.

Status of This Memo

   This Internet-Draft is submitted in full conformance with the
   provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
   Task Force (IETF).  Note that other groups may also distribute
   working documents as Internet-Drafts.  The list of current Internet-
   Drafts is at http://datatracker.ietf.org/drafts/current/.
