摘要: 群组密钥协商(GKA)是保证随后安全通信的重要手段之一。提出了一种新的群组密钥协商协议,在协议中,参与者可以通过一系列算法对其他参与者的真伪进行验证。该协议以较低的计算成本实现参与者安全的会话密钥协商,具备可容错性和长期私钥可重用性的特点。分析表明可抵抗多数常见攻击。

Abstract: Group Key Agreement (GKA) is one of the important methods to ensure the subsequent secure communication. A new group key agreement protocol was proposed in this paper. In this protocol, the participants could verify the honesty of other participants by a series of algorithms. The new protocol realized the secure session key agreement with lower computational cost. In addition, it has the fault-tolerance property and the long term key-reuse property. The performance analysis results show that this protocol can resist many common attacks.

Key words: cryptography, Group Key Agreement (GKA), fault-tolerance, expandability
