Abstract:
Security bounds for the Magma cipher CTR encryption mode with the CryptoPro Key Meshing ( CPKM ) re-keying method are obtained for the standard security model and side channel information model. A modified re-keying method better than CPKM is proposed. Operational features of the Kuznyechik cipher CTR encryption mode for several re-keying methods are discussed.
Key words:
provable security, encryption mode, block cipher, GOST, re-keying.
