The Application And Research Of Order Preserving Encryption In Ocean Environmental Information Cloud Storage Ciphertext Retrieval System

Cloud computing technology develops rapidly today and cloud storage will playan important role in the data storage in the future. The security problem in cloudcomputing has become the key issues of cloud computing rapid development andpopularization. In order to keep the data secure,we first encrypt the plaintext intociphertext,then store the ciphertext on the cloud platform. Ciphertext retrieval systemusually adopts keyword matching technology, when the keyword is a scope of data, alot of ciphertext retrieval system cannot retrieve effectively.This paper discuss the application of the order preserving encryption in the cloudstorage system of ocean environmental information in combination with thecharacteristics of the ocean environment information through the ciphertext indexproducted by the key word on the basis of the analysis and comparison with someexisting encryption algorithm.Eventually this paper implements the ocean environmental information cloudstorage ciphertext retrieval system based on order preserving encryption on the basisof the research of the above technologies and idea. The ocean environmentalinformation cloud storage ciphertext retrieval system not only can keep the data of theocean environmental information secure on the cloud platform,but also can wellcomplete the tasks of data retrieval.Therefore provide a viable way to query onciphertext in cloud storage system of ocean environmental information. In order tofurther keep the system secure, we adopt authentication technology.This technologyuse MD5combine with Salt so that it can not only make illegal user not to access thesystem but also make the user information more safer.
