After the user leases the storage space of the cloud service provider (Cloud service PROVIDER,CSP), the file is usually stored in ciphertext on the CSP in order to protect privacy. This brings a problem to search for key words in ciphertext data. In this scenario, the CSP is considered a potential attacker. A secure and efficient cloud computing scheme is proposed to support multiple keyword lookups. This scheme is based on the binary sort tree structure, in order to guarantee the security and privacy of the user's data, and to support the Multiple keyword query of the file by authorized users, so that users can enjoy multiple keyword query service anytime and anywhere.
