Title: A secure distributed group signature scheme
Abstract: A distributed group signature scheme was proposed using a standard model,and its correctness and security was also analyzed.The analysis shows that a legal group member can generate a group signature on behalf of the group,and an arbiter can open a legal signature while also having the ability to determine whether the group manager is disguised as a legitimate group member.Furthermore,this scheme takes advantage of distributed helpers to help update member keys in every time section,thus forward and backward security is implemented,and the single-point failure of a helper which would cause a group member to not be able to update is avoided.Therefore,the scheme proposed can not only resist disclosure of group member keys,but also enhance the robustness and availability of the group signature.
