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,m ICDH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。
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）.
