2008 International Symposium on Electronic Commerce and Security
5-Round Computational Zero-Knowledge Proof with Negligible Error Probability for Any NP from Any One-Way Permutation
August 03-August 05
ISBN: 978-0-7695-3258-5
We will construct a perfectly hiding commitment in two rounds from any one-way permutation, which is a negation of this result that O(n/(log n)) rounds is the tight lower bound on the rounds complexity of perfectly hiding commitments from any one-way permutation. Based on our commitments, we will construct a computational zero-knowledge proof for any NP that achieves negligible error probability in 5 rounds of interaction, assuming only the existence of a one-way permutation.
