摘要 提出了一种新的无证书的签密方案,新方案在签密过程中只需要1次配对运算,在解签密过程中仅需要4次配对运算.与已有方案相比,新方案具有更高的效率.在安全性方面,新方案满足机密性、不可伪造性和可公开验证性. A certificateless signcryption scheme is proposed. New scheme only requires one pairing operation in the signcryption phase and four pairing operations in the unsigncryption phase. Compared with the existing schemes,the new scheme is more efficient. For security requirements,this new scheme satisfies confidentiality, unforgeability and public vertifiability.
