Dynamic Cryptographic Hash Functions
William R. Speirs II Samuel S. Wagstaff
We present the dynamic cryptographic hash function, a new type of hash function which takes two parameters instead of one. The additional parameter, the security parameter, specifies the internal workings and size of the digest produced. We provide a formal definitions for a dynamic cryptographic hash function and for the traditional security properties, modified for dynamic hash functions. Two additional properties, security parameter collision resistance and digest resistance, are also defined. The additional properties are motivated by scenarios where a dynamic hash functions more cleanly provides a solution to a typical cryptographic problem.
