> 中文摘要: 无证书公钥密码体制(certificateless public key cryptography,简称CL-PKC)是在基于身份的公钥密码体制(identity-based public key cryptography,简称ID-PKC)的基础上提出来的一种新型公钥密码体制,没有密钥托管问题、不需要使用公钥证书,使得无证书公钥密码体制从其概念提出的初始就受到了学术界和工业界的极大关注.从2003 年至今,它一直是密码学和信息安全领域非常活跃的研究热点.其理论和技术在不断地丰富和发展.到目前为止,已经积累了大量的研究成果.将对这些成果进行较为系统的整理、分析、比较和简要的评述,并探讨该领域研究尚存在的不足及值得进一步研究的问题.
Abstract:Certificateless public key cryptography (CL-PKC for short) is a new type of public key cryptography, which is developed on the foundation of identity based cryptography (ID-PKC for short). CL-PKC elimilates the key escrow problem and the need for public key certificate. These two advantages are what makes it attractive to the research community and industrial world form the beginning of its birth. It has been a very active research hot topic in the field of cryptology and information security. In about seven years, the study of CL-PKC has advanced step by step, making its theories and techniques more and more enriching. This paper revisits, analyzes, compares, and briefly reviews some of the main results. Furthermore, this study discusses some existing problems in this research field that deserve further investigation.
