Extended Public Key Cryptosystem and Aggregate Key for Secure data Sharing In Cloud
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2015, Vol 4, Issue 10
Abstract
Information sharing is a basic usefulness in cloud storage. We exhibit how to immovably, powerfully, and straight forwardly impart information to others in cloud storage. Cryptographic frameworks are more versatile and every now and again connect with various keys for a solitary application. In information security, it depends on the server to execute the entrance control after confirmation. We illustrate new public key cryptosystems that make consistent size figure writings to distribute decryption rights for any arrangement of cipher texts. The secret key holder can free a consistent size aggregate key for supple decisions of cipher text set in cloud storage. In any case, the other scrambled records outside the set stay private. Every class now is indexed by a 2-level list and the quantity of classes is expanded by n for each added key. For our methodology, at most 2 total keys are required. In the long run our methodology is adaptable and powerful.
