ABSTRACT:
Hash functions are important in modern cryptography. Main applications are their use in conjunction with digital signature schemes and message authentication. Hash functions, commonly known as message authentication codes (MACs), have received widespread use in practice for data integrity and data origin authentication. New and inventive ways of building fast MACs from hash functions involve keyed hash functions in which secret keys are used at certain locations of the compression process and the keys are also hashed.
