Keyed Streebog is a secure PRF and MAC
Abstract
One of the most popular ways to turn a keyless hash function into a keyed one is the HMAC algorithm. This approach is too expensive in some cases due to double hashing. Excessive overhead can sometimes be avoided by using certain features of the hash function itself. The paper presents a simple and safe way to create a keyed cryptoalgorithm (conventionally called "Streebog-K") from hash function Streebog
