Unlinkable Randomizable Signature and Its Application in Group Signature
Sujing Zhou and Dongdai Lin
Abstract
We formalize a generic method of constructing efficient group
signatures, specifically, we define new notions of unlinkable
randomizable signature, indirectly signable signature and
Note: This is the full version of the paper at Inscrypt 07, and appended with an important note Appendix D, where it was pointed out that Camenisch and Lysyanskaya's group signature scheme proposed at Crypto'04 is actually insecure.
