Hamsi is one of the second round candidates of the SHA-3 competition. In this study, we present non-random differential properties for the compression function of Hamsi-256. Based on these properties, we first demonstrate a distinguishing attack that requires a few evaluations of the compression function. Then, we present a message recovery attack with a complexity of 210.48 compression function evaluations. Also, we present a pseudo-preimage attack for the compression function with complexity 2254.25. [ABSTRACT FROM AUTHOR] |
