内容:

This is an overview of cryptographic hash functions and its state of art. We first discuss properties, structures and generic attacks on hashing. Then we describe three basic methods of hash function design, namely, hashing based on block ciphers, custom designs, and hashing based on intractable problems. We close our presentation with a presentation of requirements and evaluation process of the NIST SHA-3 call for new hash standard.
