A New Certificateless Ring Signcryption Scheme
摘要
Abstract
Recently, in order to eliminate the use of certificates in certified public key cryptography and the key-escrow problem in identity based cryptography.the notion of certificateless public key cryptography was introduced. In this paper,a new certificateless ring signcryption scheme based on bilinear pairing is proposed. Hie message can be sent anonymously,authentication and confidentiality are guaranteed simultaneously in the scheme. The recipient can be convinced that the message has been sent by one of the members in this group, but the actual sender remains unknown. The scheme is proved to be secure in the random oracle model under the hardness assumptions of the decisional bilinear Diffie-Hellman problem. Compared with the traditional" signature men encryption" paradigm,this scheme is more effective.关键词
