This paper defines a strong security model for multi-recipient signcryption scheme in the random oracle model, which is semantically secure against adaptive chosen-ciphertext insider attack, existentially forgeable chosen-message attack and anonymous chosen-ciphertext insider attack. By analyzing, we point out that Li-Hu-Liu Multi-Recipient Signcryption Scheme is insecure against the adaptive and anonymous chosen-ciphertext insider attacks.

摘要在随机预言模型下定义了一个多接收者签密方案的强安全性模型，该模型满足适应性选择密文内部攻击安全性、选择消息抗存在性伪造和密文匿名安全性；通过分析指出， Li、Hu和Liu等人提出的多接收者签密方案，不具有适应性选择密文内部攻击安全性和密文匿名性，并给出所定义强安全性模型中的攻击方法；随后提出改进方案，该方案在强安全模型中证明是安全的。
