Quantum preimage, 2nd-preimage, and collision resistance of SHA3
Post-quantum cryptography SHA3,SHAKE
2017/4/11
SHA3 and its extendable output variant SHAKE belong to the family of sponge functions. In this work, we present formal security arguments for the quantum preimage, 2nd2nd-preimage, and collision resis...
In this note, we present a 2nd-preimage attack on AURORA-
512, which is one of the candidates for SHA-3. Our attack can generate
2nd-preimages of any given message, in particular, the attack complex...
