The invention discloses an efficient searchable access control method based on a hidden strategy CP-ABE, which belongs to the field of information security. The method is based on a public key and a main key which are generated by a cloud server and are used for encrypting data. A data owner encrypts the uploaded data and the optional search keywords respectively according to the optional access strategy and the public key, sends the ciphertext to the cloud server and sends the keyword ciphertext to the search server. After the data visitor makes an access request to the cloud server, the cloud server generates a private key according to the attribute of the visitor and sends the private key to the visitor. The visitor encrypts the selected search keyword by using the private key to generate a keyword trap door, and sends the keyword trap door to the search server for ciphertext search; the search server returns the matched ciphertext number to the visitor through the cloud server; andthe visitor decrypts the ciphertext according to the private key of the visitor, and if the access strategy is met, decryption can be successfully carried out. The method is low in operation cost andhigh in operation efficiency.
