Abstract

With the advancement of information technologies particularly cloud storage is used for outsourcing data. Now a day's users store a large amount of information on the cloud but it's untrusted and we store secure data on the cloud. To conquer this downside we suggest the idea of searchable encryption that gives promising way in resolving the privacy problem at the time of storing data to the cloud. This method consent to store the information in encryption format on an untrusted server, and then hand over the server to search on their behalf by the private key and encrypted search indices. When a file is to be shared with a group of people, lot of keys need to be generated and shared with users. A main confront to scheming such encryption method lies in the well-organized encryption key management. Our System is an advancement of key aggregate searchable encryption (KASE), where a data holder only wants to share out a single key to multiple users for allocation of the huge documents, and the user only has to offer a single trapdoor to the cloud for getting the shared documents. The safety analysis and performance estimation confirm that the given method is probably safe and practically capable.
