title = "Cryptanalysis of two group signature schemes",
abstract = "Group signature schemes allow a group member to anonymously sign on group{\textquoteright}s behalf. Moreover, in case of anonymity misuse, a group authority can recover the issuer of a signature. This paper analyzes the security of two group signature schemes recently proposed by Tseng and Jan. We show that both schemes are universally forgeable, that is, anyone (not necessarily a group member) is able to produce a valid group signature on an arbitrary message, which cannot be traced by the group authority.",
