Abstract

Abstract: Certificateless public key cryptography resolves the key escrow problem and public key authentication problem.A certificateless ring signcryption scheme which modifies the key generation algorithms of Selvi et al’s ID-based ring signcryption scheme is proposed.In the random oracle model，the scheme is provably secure against adaptive chosen ciphertext attacks.

Key words: certificateless signature, ring signcryption, bilinear pairings

摘要： 无证书公钥密码体制解决了密钥托管问题和公钥认证问题。通过修改Selvi等人提出的基于身份的环签密方案中的密钥的产生算法，提出了一个无证书环签密方案。在随机预言模型下，该方案在适应性选择密文攻击下是可证明安全的。
