Short Group Signature without Random Oracles.
Xiaohui Liang, Zhenfu Cao, Jun Shao, Huang Lin · 2007
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 [9], BW07 [10], ours is more practical due to the short size of both public key and group signature.
