摘要: 针对传感器节点与互联网主机通信安全性较低的问题,提出一种CLPKC-to-TPKC在线/离线异构签密方案。该方案结合在线/离线技术,定义从无证书公钥密码到传统公钥密码环境的形式化安全模型,并在随机预言模型下基于q-SDH,mICDH和BDHI困难假设问题,证明方案的安全性。分析结果表明,与IDPKC-to-CLPKC在线/离线异构签密方案相比,该方案只需要2个双线性对运算,具有更高的运算效率,适用于无线传感器网络。

Abstract: Aiming at the weak security problem of communication between the sensor nodes and the Internet hosts,a CLPKC-to-TPKC online/offline Heterogeneous Signcryption(HSC) scheme is proposed.Based on the online/offline technology,this paper defines a formalized security model from the certificateless public key cryptography to the traditional public key cryptography environment.In the random oracle model,based on q-SDH,mICDH and BDHI difficult assumption problem,the scheme is proved to satisfy the security requirement.Analysis results show that compared with the IDPKC-to-CLPKC online/offline heterogeneous signcryption scheme,the proposed scheme is more efficient for only using two bilinear pairs of operations,so it is suitable for Wireless Sensor Network(WSN).
