摘要：

Ciphertext-auditability of public key encryption scheme means that the ciphertext should been verified by any-one whether it was actually created by the public key. It also should satisfy two additional requirements: 1) no adversary can create a valid-looking ciphertext and then it can pass the verification process together with a public key and a plaintext; 2) the plaintext cannot be revealed from ciphertext without the help of the cor- rect private key. This paper, in the first time, proposes an ciphertext-auditable identity-based encryption. Our scheme doesn't need the certificates and the sender can di- rectly encrypt message via using the identity without the progress of public key authentication. Furthermore, the proposed scheme is provably secure under the standard model against the k-resilient ciphertext-auditability.
