摘要: Cloud computing allows data owner to outsource its whole information infrastructure cloud service provider (CSP).Authorized users can search the they want through cloud. However malicious CSP may not execute users’ query but returns that there is no result matches condition for economic benefit .In this paper, we propose a mechanism solve problem in owner-write-user-read applications. We add redundant generated by hash function original data. When adding query, cannot return empty because of must exist Through adoption key derivation method, needs maintain only few seeds. Analysis shows procedure using owner’s and will introduce limited storage overhead.
