Wei Yuan, Liang Qing Hu, Hongtu Li, Jianfeng Chu · Applied Mathematics & Information Sciences · 2013
In this paper, a novel and efficent password based group key exchange protocol with secret sharing is proposed. Secret sharing technology is usually used to control the privileges of the authorized users to improve the robustness of the system in past years. The results are applied into designing the key exchange protocol directly, which clarify the proposed scheme. The security analysis shows the proposed scheme can provide the confidentiality and authentication, while being competitively efficent in comparison with other works in the literature.
