2009年，Han等人提出了一种用于无基础设施无线网络的高效门限自愈密钥分发方案。他们声称密钥分发方案满足前向安全性，即，任何已被撤销的内部用户都不能生成新的会话密钥。本文提出了一种针对该密钥分配方案前向安全性的攻击方法。此外，该攻击方法还可以应用于该方案的后向安全性，从而使原门限自愈密钥分配方案不安全。
In 2009, Han et al. proposed an efficient threshold self-healing key distribution scheme with sponsorization for infrastructureless wireless networks. They claimed that the key distribution scheme satisfies the forward security, i.e., any internal user who has been revoked can not generate a new session key. In this paper,an attack method against this key distribution scheme's forward security was presented. Furthermore, this attack method can also be applied to this scheme's backward security.Thus,the original threshold self-healing key distribution scheme is insecure.
