摘要:
 无证书聚合签密是把多个用户对不同消息产生的不同签密聚合成一个签密,不仅保证信息传输的机密性和认证性,而且降低了信息传输的功耗,因此应用于大规模分布式通信中的多对一模式.聚合签密方案大多需要进行双线性对运算,效率不高.为此,提出了一种高效的无线性对的无证书聚合签密方案.该方案在随机预言模型下应用离散对数,对原有的无双线性对聚合签名算法进行了改进,形成了更为安全、高效的聚合签密方案.基于所提出的聚合签密方案安全模型,分析研究了随机预言模型下提出方案的不可伪造性和机密性,并对其有效性和可行性进行了验证.理论分析表明,所提出的方案在多个签密者存在的条件下,不仅具有机密性、不可伪造性,还具有更高的计算效率.
Abstract:
 Certificateless aggregate signcryption scheme can aggregate different signcryptions generated by multi-users corresponding to various information into one signcryption,which can not only ensure the confidentiality and certification in information transmission but also reduce power dissipation.Therefore,it is applied in the multiple-to-single mode in large-scale distributed communication.Most aggregate signcryption schemes need computation of bilinear pairing with poor efficiency.For that,an efficient certificateless aggregate signcryption schemes without bilinear pairing is proposed,where disperse logarithm is employed in random oracle model to improve the original aggregate signature algorithm without bilinear pairing for safer and more effective one.Based on the proposed aggregate signcryption security model,investigation and analysis on the presented scheme with random oracle model is performed and validation on its effectiveness and feasibility also conducted.Theoretical analysis shows that in the presence of multiple signcrypter it owns not only the confidentiality and unforgeability but also higher computational efficiency.
