Error Propagation in Various Cipher Block Modes
Karel Burda · 2006
In this paper, we examine the problem of error propagation in various cipher block modes. We analyze the modes which are used for link encryption devices, i.e. ECB, CBC, CFB, OFB and CRT modes. The dependence between input and output error probability of the modes is derived in the paper. The results obtained can be used to choose the block cipher and its mode or to find the threshold channel error probability. Key words: Error propagation, cipher block mode, error probability, block cipher. 1.
