....is made to [8] anywhere. Corollary 8 can be found in [13] together with a sketch of (a different) proof. To the best of our knowledge, the representation problem for groups of prime order has furthermore been used as a tool in a handful of articles. For commitment purposes, it was used in [33] [2] and in the confirmation protocol of undeniable signatures ( 9, 10] all with k = 2. Furthermore, it has been put to use for signatures unconditionally secure for the signer in [13] and [24] fail stop signatures, k = 2) and for an identification scheme unconditionally secure for the prover in ....

....change the bit committed to relies on specific number theoretic assumptions. More general assumptions are used in [24] which can be based on any collision intractable hash function, and [23] based on any one way permutation. Unconditionally hiding multi bit commitment schemes were presented in [3, 26, 9, 2]. They all rely on specific number theoretic assumptions, the hardness of computing discrete logarithms or factoring integers. In contrast, our scheme is based on any collision intractable hash function. This is an improvement in theory, because the assumption is weaker, and useful in practice, ....
