Title:
Short Group Signature without Random Oracles
Authors: Xiaohui Liang, Zhenfu Cao, Jun Shao, Huang Lin
Abstract:We construct a short group signature which is proven secure without random oracles. By making certain reasonable assumptions and applying the technique of non-interactive proof system, we prove that our scheme is full anonymity and full traceability. Compared with other related works, such as BW06, BW07, ours is more practical due to the short size of both public key and group signature.
