【Abstract】 In this paper we propose new group signature schemes which overcomes some problems ,such as the length of the public key is linear in the size of the group etc.Furthermore,the scheme allows the group manager to add new members to the group without modifying the public key.The realization is based on the knowledge of signature of DSA.更多还原
