A Secure Group Signature Scheme
摘要
Group signature scheme could be applied to the valid members to represent the group. The validity of the signature could be verified by the receiver. On the other hand, the member who signs the message could not be found. However, the group manager could reveal and identify the signer if it is necessary. Concerning with a high performance on security, a new group signature scheme based on a discrete logarithm problem to achieve the characteristics of group signatures is proposed. With this proposed scheme, the signature could be generated rapidly. Also, the verification procedure of the group signature could be spent in a short time. This group signature scheme can protect important messages. Compare with other schemes, the proposed scheme is more secure and efficient than others. The analysis of the security and the performance evaluation of the proposed scheme are provided. The proposed group signature scheme could be suitable for e-commerce applications.
