摘要：Cloud computing has become an integral part of IT industry. As it becomes prevalent, more and more sensitive information are being centralized in the cloud. A user stores his files in a cloud, and retrieves them whenever he wants to use them. This avoids the cost of maintaining as there is no need to personally install them on one's computer. But there is an extreme need for privacy of the data and the ability to search it without losing privacy. The users search their documents through keyword in plaintext. There is a cloud service provider (CSP), whose purpose is to provide more and more security and privacy. To keep user data confidential against an unfrosted CSP, an easy way is to apply cryptographic approaches, by disclosing the data decryption key only to authorized users. Thus the keyword privacy is maintained. In this paper, we define different types of keyword searching techniques.
