....need a collision resistant hash function actually, as we shall see, a universal oneway hash function [16] is sufficient. This is a revision of IBM Research Report RZ 3083 (December 1998) 1 Our new schemes are interesting in that they are state free, unlike other provably secure schemes [11, 9, 7]. Of course, we achieve this at the expense using of a potentially stronger assumption than is made in [11, 9, 7] We stress that in discussing proofs of security, we are not making use of the random oracle model of computation [3] but rather, we are working in the real world of computation. ....

....attack, as defined in [9] To prove that our new schemes are secure, we need to make the Strong RSA Assumption (SRA) recently introduced by [2] We also need a collision resistant hash function. 1 Our new schemes are interesting in that they are state free, unlike other provably secure schemes [9, 7, 6]. Of course, we achieve this at the expense using of a potentially stronger assumption than is made in [9, 7, 6] 1 We could get by using a target collision resistant hash function by adapting the ideas from [4] We stress that in discussing proofs of security, we are not making use of the ....
