(in English) |
It is an open question whether there exists an efficient double-block-length hash function such that time complexity of any collision-finding algorithm against it is $\Omega(2^{\ell/2})$, where $\ell$ is the length of the output. In this article, a partial but affirmative answer is given to this
question in a black-box model. The answer is partial because it is assumed that two different block ciphers are used in the hash functions for the security proofs. |
