Abstract: Signcryption offers authentication and encryption for a message and simultaneously costs less.A new certificate-less signcryption scheme is proposed,and proves secure under the strong security model.In the scheme,anyone can signcrypt any information by the receiver′s identity,public key,his own partial private key and the secret value.The receiver can decrypt the ciphertext by his own partial private key and the secret value,and then he can identify whether the sender is the actual signcrypter.In the scheme,we only need two pairing operations in unsigncryption without pairing operation in signcryption.Compared with existing schemes,the computation cost of the proposed scheme is less.
