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.

摘要在隨機(jī)預(yù)言模型下定義了一個(gè)多接收者簽密方案的強(qiáng)安全性模型国产一级毛片国产一级A片，該模型滿足適應(yīng)性選擇密文內(nèi)部攻擊安全性、選擇消息抗存在性偽造和密文匿名安全性偷拍网久久网站；通過分析指出AVwww网站在线， Li、Hu和Liu等人提出的多接收者簽密方案学生妹人人操，不具有適應(yīng)性選擇密文內(nèi)部攻擊安全性和密文匿名性国产AV黄色，并給出所定義強(qiáng)安全性模型中的攻擊方法；隨后提出改進(jìn)方案我想看黄色一级高清无码视频，該方案在強(qiáng)安全模型中證明是安全的国产高清色色。

Unfortunately,in this work, security analysis was given to the scheme and results showed that the scheme was forgeable and repudiative.

We show that it is secure against existential forgeable on adaptively chosen message and ID attack under the random oracle.
