| Abstract(in English) | In this report, we discuss sufficient conditions for collision-free iterated hash functions. First, it is shown that a kind of iterated hash functions based on block ciphers are not necessarily collision-free even if the block ciphers are secure against the chosen plaintext attack. This result is applicable to many of the proposed schemes, such as Rabin scheme, Davies-Meyer scheme and so on. Second, we investigate the relationship between two input sequences which are transformed to the same sequence by iterated hash functions and show sufficient conditions on round functions for iterated hash functions to be collision-free. |
