In this paper, we propose a large universe ciphertext-policy attribute based encryption (ABE) scheme with efficient revocation. To achieve the revocation, we divide the master key into two parts: delegation key and secret key, which are sent to the cloud provider and user separately. Note that, our scheme is proved selectively secure in the standard model under q-type assumption. Finally, we give the concrete analysis associated with our scheme including security requirements, functionality and performance.
