Trust Based Certificate Revocation of Malicious Nodes in MANET

Trust Based Certificate Revocation of Malicious Nodes in MANET MANET (Mobile Ad hoc Network) is an autonomous, robustness and scalable system of mobile nodes communicating via wireless links with no rigid infrastructure. Owing to the independent and dynamic nature of mobile nodes, topology of MANET often changes and is prone to various attacks. To eradicate the security threats, an efficient certificate revocation scheme is adopted to attain a secure communication. Conventional schemes in MANETs aims to achieve greater security by electing a Cluster Head (CH) for each clusters which governs…

Secure Data Deduplication with Dynamic Ownership Management in Cloud Storage

Secure Data Deduplication with Dynamic Ownership Management in Cloud Storage In cloud storage services, deduplication technology is commonly used to reduce the space and bandwidth requirements of services by eliminating redundant data and storing only a single copy of them. Deduplication is most effective when multiple users outsource the same data to the cloud storage, but it raises issues relating to security and ownership. Proof of-ownership schemes allow any owner of the same data to prove to the cloud storage server that he owns the data in a robust way.…
