Description

In wireless body area network, the security is critical between the client and the application providers. So we propose a remote authentication protocol based on the certificate less cryptography for extra body communication in WBAN. The proposed revocation mechanism is highly suitable for the large scale WBAN. The security key is updated in the trusted party authentication. Caching frequently accessed information at the clients is an effective strategy to enhance the performance in mobile environments. When caching is used, information available in the server is duplicated on the caching nodes. Cooperative caching improves system performance because it allows sharing and coordination of cached data among multiple mobile users in the network. Several protocols have been proposed to improve data accessibility and reduce query delay in MANETs. Some of these proposals have adopted the cooperative caching scheme, allowing multiple mobile hosts within a neighborhood to cache and share data items in their local caches. In existing system Ant Colony Optimization meta heuristic is used for the NP-hard scheduling problem. In this project, the system proposes a remote authentication protocol featured with nonrepudiation, client anonymity, key escrow resistance, and revocability for extra-body communication in the WBANs.
