A System to Minimize The Storing And Managing Secret Keys Expense Using KAC
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2015, Vol 4, Issue 10
Abstract
Emerging new computing technology cloud offering storage services. But now focus of data sharing with others in secure and efficient manner. For this the new expandable public-key cryptosystems which derives fixed-size ciphertexts .In this transforming multiple keys as single secret key. The generated single secret key sent to others or be stored in a smart card with very limited secure storage. We provide if a user needs to classify his ciphertexts into more Than n classes, he can register for additional key pairs. Each class now is indexed by a 2-level index and the number of classes is increased by n for each added key. For our approach, at most 2 aggregate keys are needed. Eventually our approach is flexible and effective.
