摘要
签密是把加密和签名结合起来,能实现数据的机密性和认证性.无证书密码体制实现无公钥证书且没有密钥托管的性质.本文提出的方案是一种基于无证书的公钥可验证签密方案,该方案在Al-Riyami提出的安全证明模型中具有机密性和不可伪造性.
Signcryption combines the signature and the encryption into one, and implements data confidentiality and authentication. Certificateless cryptosystem realizes the properties of the certificateless and the key-unescrow. So certificateless verifiable signcryption was proposed. The confidentiality and unforgeability of this scheme was proved under the secure model mentioned by Al-Riyam.
