Abstract :
Family of parameterized hash algorithms - PHAL is a proposal of a new dedicated hash algorithm designed as an answer to weaknesses of MD/SHA hash function family. Recently proposed attacks on wellknown and widely used hash functions motivate a design of new hash functions. In this paper new approach is presented, where few elements of hash function are parameterized. This approach makes the hash algorithm more secure and more flexible. PHAL consists of two mechanisms: new iteration schema and dedicated compression function.
