- Abstract
- A group signature system includes: a key issuer server for generating a first parameter of a group public key, generating a corresponding master issuing key, and issuing a signature key to a user when a user device joins; an opener server for generating a second parameter of the group public key, and a corresponding master opening key and master linking key; and a linker server for checking whether two valid signatures have been linked by using the master linking key when the two signatures corresponding to a group public key are given. The group signature system further includes: a signature verifying unit for confirming a validity of the given signatures and a signer information confirming unit for confirming a validity of singer confirming information generated by the opener server.
