摘要：The advantage of storage as a service manyenterprises are moving their valuable data to the cloud, sinceit costs less, easily scalable and can be accessed fromanywhere any time. The trust between cloud user andprovider is paramount. They use security as a parameter toestablish trust. Cryptography is one way of establishing trust.Searchable encryption is a cryptographic method to providesecurity. In literature many researchers have been working ondeveloping efficient searchable encryption schemes. Toprotect data privacy, the sensitive data should be encrypted bythe data owner before outsourcing, which makes thetraditional and efficient plaintext keyword search techniqueuseless. Hence, it is an important to explore secure encryptedcloud data search service. Considering the huge number ofoutsourced data, there are three problems we are focused onto enable efficient search service: multi-keyword search, resultrelevance ranking and dynamic update. In this study wepresent the comparative analysis of searching methods forkeyword over cloud as well as various encryption techniqueswhich is used for data security.
