An Efficient Certificateless Signcryption Scheme without Random Oracles
摘要
Certificateless signcryption is an important multi-function cryptography primitive which solves the key escrow problem in the identity-based cryptosystem and simplifies the certificates management problem in the traditional public key cryptosystem. It simultaneously fulfils the integrated function of public encryption and digital signature with a computing and communication cost significantly smaller than that required by the signature-then-encryption method. In this paper, we propose an efficient certificateless signcryption scheme secure in the standard model. The proposed scheme satisfies the message confidentiality and unforgeability.
