摘要: 签密是一种能在一个逻辑步骤内同时提供消息的机密性和消息源认证性的密码原语。针对目前基于双线性对的无证书聚合签密(CLASC)方案效率较低的问题,提出了一种新的基于双线性对的无证书聚合签密方案。在该方案中,任何用户均可作为聚合者发起签密协议。用户生成签密密文后,密文被发送给聚合者进行聚合。安全性分析证明了该方案在随机预言模型下满足不可伪造性和保密性。对比结果表明所提方案仅要求每位签密者进行一次对运算,能够提高计算效率,有利于对实时性要求较高的应用。

Abstract: Signcryption is a cryptography primitive which can provide message confidentiality and sender authentication in a single logic step. In order to improve computational efficiency of certificateless aggregate signcryption scheme based on bilinear pairings, a new CertificateLess Aggregate SignCryption (CLASC) scheme based on bilinear pairings was proposed. In the proposed scheme, any user could be allowed to be an aggregator to initiate the signcryption protocol. After signcryption ciphertexts were generated by users, the ciphertexts were sent to the aggregator for aggregating to be one single ciphertext. The scheme was proved to be existentially unforgeable and confidential under the random oracle model through security analysis. The comparison results show that the proposed scheme only requires pairings operation only once for each signcryption user, which can improve the computational efficiency and can be applied to applications with high real-time requirements.
