In this paper, we construct a certificateless concurrent signcryption scheme and an efficient fair exchange protocol, and show that the proposed scheme is secure under the Diffie-Hellman assumptions in the random oracle. As compared with the recently proposed concurrent signcryption scheme, our scheme has better performance in term of the security and computation overheads.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e要約(英語): \u003c\/strong\u003eCertificateless cryptography achieves the best of the two worlds: it inherits from identity-based techniques a solution to the certificate management problem in public-key encryption, whilst removing the secret key escrow functionality inherent to the identity-based setting.
