    abstract =  {This document defines a set of encryption transforms for use in the Encapsulating Security Payload (ESP) and in the Internet Key Exchange version 2 (IKEv2) protocols which are parts of the IP Security (IPsec) protocols suite. The transforms are based on the GOST R 34.12-2015 block ciphers (which are named "Magma" and "Kuznyechik") in a Multilinear Galois Mode (MGM) and the external re-keying approach. This specification is developed to facilitate implementations that wish to support the GOST algorithms. This document does not imply IETF endorsement of the cryptographic algorithms used in this document.},
