Domain Extenders for UOWHF: A Finite Binary Tree Algorithm

Palash Sarkar

Abstract

We obtain a {\em finite} binary tree algorithm to extend the domain of a UOWHF. The associated key length expansion is only a constant number of bits more than the minimum possible. Our finite binary tree algorithm is a practical parallel algorithm to securely extend the domain of a UOWHF. Also the speed-up obtained by our algorithm is approximately proportional to the number of processors.
