IMPROVING SECURITY AND EFFICIENCY IN ATTRIBUTE BASED DATA SHARING USING CLOUD COMPUTING

Abstract

For secure information partaking in cloud figure content approach property based encryption is promising
on the grounds that information proprietor having full control over access arrangement of shared information. However,
CP-ABE having a key escrow issue whereby the mystery keys of clients must be issued by a trusted key specialist. CPABE plans can't bolster property with self-assertive state. So we return to credit based information sharing to settle the
key escrow issue yet in addition enhance the expressiveness of property, so the subsequent plan is all the more agreeable
to distributed computing applications. We propose an enhanced two-party key issuing convention that can Guarantee
that neither key specialist nor cloud specialist co-op can trade off the entire mystery key of a client exclusively. In
addition, we present the idea of property with weight, being given to upgrade the declaration of characteristic, which can
not just stretch out the articulation from twofold to subjective state, yet in addition help the unpredictability of access
strategy.
