Security and DependableEquivalent Service Using Fuzzy Identity-Based Encryption

Abstract

In cloud computing data centers is take a virtual servers and organization pay as the capacity of usedata centers offers and provideservices by use of virtualization techniques. Computer network storage are the principle offering of information transfers. The context of publish/subscribe is only authenticated publisher are allowed to disseminate events in the cloud and only those events is delivered to authorized subscribers. Fuzzy Identity-Based Encryption (FIBE) scheme is proposed for secure publisher/subscriber data destitution in cloud servers. FIBE uses Advanced Encryption standard (AES) is based on Symmetric Key Algorithm.We present a contentbased publish/subscribe function is routed over a peer-to-peer network model. The implications of combining methods is explored and a particular implementation. We exploit hierarchical key derivation algorithms to encode publication-subscription matching semantics for scalable key management and develop a probabilistic number of event routing algorithm to minimize the small information that can be inferred by the routing nodes. An experimental evaluation of our prototype model the PS Guard meets the security requirements while modify the performance and security of a pub-sub network.
