Colliding Message Pair for 53-Step HAS-160
We present a collision attack on the hash function HAS-160 reduced to 53-steps. The attack has a complexity of about 235 hash computations. The attack is based on the work of Cho e...

MD4 is Not One-Way
MD4 is a hash function introduced by Rivest in 1990. It is still used in some contexts, and the most commonly used hash function (MD5, SHA-1, SHA-2) are based on the design princip...

New Proofs for
HMAC was proved in [3] to be a PRF assuming that (1) the underlying compression function is a PRF, and (2) the iterated hash function is weakly collision-resistant. However, recent...

SMASH - A Cryptographic Hash Function
1 This paper presents a new hash function design, which is different from the popular designs of the MD4-family. Seen in the light of recent attacks on MD4, MD5, SHA-0, SHA-1, and...
