A multi keyword top k search schema for efficient query processing over encrypted data

computer science engineering

Cloud computing deliver computing resources, services and virtual management applications over web. Such applications contain sensitive information and the data must be secured from the storage unauthorized third parties and cloud service providers. The privacy and respectability of the information needs to protected during the capacity and transmission. Before the information is redistributed to the servers the information must be encoded utilizing a solid security saving encryption algorithm that must likewise strengthens effective looking over scrambled information. So, to encrypt the information the symmetric AES encryption technique is utilized in applications like HTTP and OFTP.. The cloud server practices an index to search the encrypted data deposited in it to complete the request from the client which is built using the Random traversal algorithm. During the information retrieval, the cloud server uses the Random Group Multi keyword Top – k Search scheme to calculate the relevant scores of each document in the index and display the results to the user. In Random Group Multi keyword top – k Search algorithm the framework overwhelmed the problem of query unlink skill and hiding the access patterns from the cloud server.
