摘要：With the rapid development of information usage in society in the recent years, cloud systems are beingmore frequently used by Internet users. Among the many functions of cloud systems, the uploading and downloadingfiles are more often used. But if the numbers of files are numerous, the keys which can decrypt the downloading filesare also numerous. We address this practical problem by proposing key aggregate method with searchable encryption,in which a data owner only needs to distribute a single key to a user for sharing a large number of documents, and theuser only needs to submit a single trapdoor to the cloud for querying the shared documents. The encrypted data issearch by trapdoor on cloud. Trapdoor is created by end user. To share the security key we have used secure electronicmailing system. The result of proposed system shows that our system is efficient and secure for cloud data sharing.
