Practical Collisions for SHAMATA-256the AES, and it is one of the fastest submitted hash functions. In our attack, we show weaknesses in the message injection and state update of SHAMATA. It is possible to find certain message differences that do not get changed by the message expansion and non-linear part of the state update function

Cryptanalyses of Narrow-Pipe Mode of Operation in AURORA-512 Hash Function a second-preimage attack on AURORA-512/-384 and explain that the randomized hashing can also be attacked. We finally show a full key-recovery attack on HMAC-AURORA-512 and universal forgery on HMAC-AURORA-384. Our attack exploits weaknesses in a narrow-pipe mode of operation of AURORA-512 named “Do

More on Key Wrappingnagement architectures, often to create an “adapter layer” between incompatible legacy systems. Although in principle any secure encryption scheme can be used for key wrapping, practical constraints (which are commonplace when dealing with legacy systems) may severely limit the possible implementati
