摘要：An efficient cryptographic approach for data sharing where datailsshared among a group of users asData sharing is an important functionality in cloud storage. How to securely and efficientlyshare a collection of datarelated to any subject areas with others in cloud storage. Development of new novel concept of Key- AggregateSearchable Encryption (KASE). This concept is implemented through development of a concrete key-aggregatesearchable encryption framework scheme. This scheme is described as where a data owner only needs to generate anddistribute a single aggregate key to a data user for sharing a large number of documents and on the other side user onlyneeds to submit a single aggregate trapdoor to the cloud server, so that he/she can query over the shared documents bythe help of generated single aggregate trapdoor. This proposesscheme is perfectly more secure and practically efficient.It is an effective method which is considered as best solution to build a practical data sharing system based on publiccloud storage. A detailed review of various methods used for data access controls and encryption is presentedand abrief comparison among the discussed methods is given.Multi cloud scheme reduce storage overhead of thecustomer bycompressing the data and reduce computationaloverhead of the cloud storage server.
