摘要：In cloud, there is an important functionality called Data sharing. Data sharing is also concerned aboutthe security, efficiency and flexibility for the data to share in the cloud storage. The capacity of selectively sharingencrypted data with different users via public cloud server may great ease security concerned over inattentive data leaksin the cloud. The key challenging of designing encryption scheme is lies between the efficient management ofencryption keys. Here address the practical problem which is largely neglected in the literature. By proposing the novelconcept of Key-aggregate searchable encryption and also instantiating the concept through concrete KASE schemewhere the data owner need to distribute a single key to data user for sharing large number of documents, and the useronly needs to submit a single trapdoor to cloud for querying the shared documents. A new public-key cryptosystem isintroduced to produce a constant size cipher text called KASE. Based on the text methodology as a key the key is usedto share the data safely. Once the sharing is completed the key aggregate differs from key aggregate cryptosystem andthis process provides efficient solution than the existing system.
