Abstract
The security evaluation of a class of block ciphers based on chaotic maps against differential and linear attacks is studied. If the round function is bijective and its maximum differential and linear characteristic probabilities are p and q respectively, the upper bounds of maximum differential and linear characteristic probabilities for r rounds are pr-1and qr-1 respectively.
