The Keccak hash function is one of the five finalists in NIST’s SHA-3 competition, and so far it showed remarkable resistance against practical collision finding attacks: Afte...
A black-box combiner for collision resistant hash functions (CRHF) is a construction which given black-box access to two hash functions is collision resistant if at least one of th...
Since Bellare and Ristenpart showed a multi-property preserving domain extension transform, the problem of the construction for multi-property hash functions has been reduced to th...
We study the influence of collision-finding attacks on the security of time-stamping schemes. We distinguish between client-side hash functions used to shorten the documents befo...
Abstract. In the context of iterated hash functions, "dithering" designates the technique of adding an iteration-dependent input to the compression function in order to d...
