Construction of universal one-way hash functions: Tree hashing revisited
AbstractWe present a binary tree based parallel algorithm for extending the domain of a universal one-way hash function (UOWHF). For t⩾2, our algorithm extends the domain from the set of all n-bit strings to the set of all ((2t-1)(n-m)+m)-bit strings, where m is the length of the message digest. The associated increase in key length is 2m bits for t=2; m(t+1) bits for 3⩽t⩽6 and m×(t+⌊log2(t-1)⌋) bits for t⩾7.
