Abstract
The short group signature introduced by Boneh et al. is one of famous anonymous signature schemes. However, for applying it to the real applications, several restrictions should be considered. The perfect anonymity of users, which is given by group signatures, prevents service providers to provide certain services or resources. For this reason, the local linkability which reduces the anonymity of users has to be provided to the service providers. In addition, the group signature keys, which are one-sidedly assigned from a group manager, cannot support the strong exculpability of users. Hence, the short group signature has to be modified for supporting the strong exculpability. In this paper, we perform a study on the use of the short group signature by proposing a few methods for supporting those two properties.
