However, to build a cloud storage services must rely on the implementations of virtualization and security mechanisms. When the users access the cloud data via Internet, the security mechanism must be able to avoid unauthorized access, distinguish the required data from different users and applications, provide the encryption and search for the storage data, and such on. However, when the data is stored in the database with Ciphertext type, the Data Manager will not be able to search the data by keyword. Therefore, an efficient ciphertext search technique for cloud storage service is very important, the technique can ensure the data confidentiality by using ciphertext and allow the administrator can search the data by keyword. According to this, the research designs an encrypted search technology which utilizes the multi-keyword to search the encrypted data, and utilizes the technology to achieve data security for cloud storage.
