| 摘 要： | 为了解决聚合签密方案中存在的密钥泄漏问题，在无限制身份基聚合签密方案的基础上，设计出一个抗身份密钥泄漏所需的身份基哈希证明系统，证明了其解封正确性、合法/非法密文不可区分性、平滑性和普遍性。基于该身份基哈希证明系统，结合随机数提取器，构造了一个抗泄漏的身份基签密方案，并给出了方案的安全证明，结果表明，其身份密钥的泄漏比值可达1-o(1)。

| Abstract: | In order to solve the problem of secret key leakage in aggregate signcryption, an identity-based hash proof system based on unrestricted identity-based aggregate signcryption scheme is constructed, and its correctness of decapsulation, valid/invalid ciphertext indistinguishability, smoothness and universality are also proved. Then, with the randomness extractor, a leakage resilient identity-based aggregate sign-cryption scheme is constructed, in which the leakage rate of identity-based secret key can be achieved to 1-o(1). Finally, the security proof of this leakage resilient scheme is also provided. |
