On High-Rate Cryptographic Compression Functions
Hash functions compression functions block ciphers

The security of iterated hash functions relies on the properties
of underlying compression functions. We study highly ecient compression
functions based on block ciphers. We propose a model for hig...
Indifferentiability of Single-Block-Length and Rate-1 Compression Functions
Single-Block-Length Rate-1 Compression Functions
2009/1/9
The security notion of indiferentiability was proposed by Maurer, Renner, and Holenstein
in 2004. In 2005, Coron, Dodis, Malinaud, and Puniya discussed the indifferentiability of hash
functions. The...
