| 摘 要： | 通过分析Wang等12]关于BF-IBE的密钥分发方案,指出其潜在的数据库泄露攻击与篡改攻击;由于Geisler等15]的关于SK-IBE的密钥产生方案未提出安全密钥分发协议,因此对前两者进行改进并提出一种关于SM9的可分离匿名分布式密钥产生分发(SADKI)方案。与几种同类型方案对比结果表明,该方案是安全高效的,实现了无对运算,不需要安全通道,具有可分离和匿名性,能够抵抗KGC数据库泄露攻击、篡改攻击、离线口令攻击。

| Abstract: | By analyzing the key issuing scheme of BF-IBE proposed by Wang et al.,this paper points out the potential database leakage attack and tamper attack.As Geisler et al s key generation scheme of SK-IBE does not propose the secure key issuing protocol,this paper improves both schemes and proposes a separable anonymous distributed key issuing(SADKI)scheme of SM9.Compared with several similar schemes,the results show that the scheme is safe and efficient.It achieves non-pairing operation,does not need a secure channel,and has separable and anonymous attribute.And it can resist KGC database leak attacks,tamper attack and offline password attacks. |
