摘要: 利用动态累加器的证人能够证明特定累加项是否参与累加的特性,实现了组成员身份认证,提出了一种新的支持节点动态增加和撤销的组密钥管理方案DAAG。在需要建立组密钥时,所有成员节点提供自己持有的累加项,参与累加计算。DAAG方案在保证成员节点证人机密性的基础上, 通过绑定证人与组密钥更新计算,限制了非成员节点对新密钥的计算能力。安全性和性能分析表明,DAAG方案虽比FM方案消耗更多的通信代价,但能够抵抗伪造、重放和共谋等恶意攻击,提供前后向安全性。
Abstract: Witnesses of a dynamic accumulator (DA) can ensure whether an object has been accumulated. On the basis of this, node membership in a cluster was verified and a novel authenticated group key management protocol was proposed, which supports node revocation and addition. In order to establish a group key for a cluster, each member provides their assigned number to join accumulation. DAAG can not only guarantee the confidentiality of witnesses, but also keep non-members from calculating novel group keys by binding witness with group key update. The security and performance analyses show that DAAG is resistant against replay attack, forgery attack and collusion attack, and can provide forward security and backward security.
