Secure Configuration of Ciphers/MACs/Kex available in SSH

In cryptography, a cipher block chaining message authentication code (CBC-MAC) is a technique for constructing a message authentication code (MAC) from a block cipher. The message is encrypted with some block cipher algorithm in cipher block chaining (CBC) mode to create a chain of blocks such that each block … See more If the block cipher used is secure (meaning that it is a pseudorandom permutation), then CBC-MAC is secure for fixed-length messages. However, by itself, it is not secure for variable-length messages. Thus, … See more As with many cryptographic schemes, naïve use of ciphers and other protocols may lead to attacks being possible, reducing the effectiveness of the cryptographic … See more • CMAC – A block-cipher–based MAC algorithm which is secure for messages of different lengths (recommended by NIST). • OMAC See more FIPS PUB 113 Computer Data Authentication is a (now obsolete) U.S. government standard that specified the CBC-MAC … See more WebConfiguring Ciphers and MACs.
