摘要
针对特定场景中群组成员间的隐私及安全通信问题,提出了一个新的可认讧的安全组织隐藏密钥协商协议。该协议以短签名算法及安全的聚合签名的广播方案(Aggregatable Signature-Based Broadcast,ASBB)为基础,基于k-BDHE假设实现了理论安全性,并且该协议实现了组织隐藏。通过与Jarecki提出的协议进行对比,结果表明,该协议在轮数及安全效率上更具有优势。
For the security of communication between group members in a specific scenario, a group secret handshake protocol is proposed. This protocol based on bilinear parings and the Aggregatable Signature-Based Broadcast (ASBB), has implemented the security with k-BDHE hypothesis affiliation hiding is realized in the protocol. Compared with the protocol proposed by Jarecki, the new one has more advantages on the round numbers and efficiency on safety.
