ABE Data Transfer viva Key Authorities between Sender & Reviser by using Strong Nodes

Abstract

In military environments, like battlefield or a hostile region, the mobile nodes might suffer from intermittent network connectivity and frequent partitions. Disruption-tolerant network (DTN) technology is the successful solution that allow, wireless devices carried by soldiers to communicate with each other and access the confidential information or command reliably by exploiting external storage nodes. It introduces several security and privacy challenges with regard to the attribute revocation, key escrow, and coordination of attributes issued from different authorities. Here, a scheme where decentralized DTNs use CP-ABE with multiple key authorities to manage their attributes with mutual communication is used. Mobile nodes in military environments such as a battlefield or a hostile region are likely to suffer from intermittent network connectivity and frequent partitions. Disruption-tolerant network (DTN) technologies are becoming successful solutions that allow wireless devices carried by soldiers to communicate with each other and access the confidential information or command reliably by exploiting external storage nodes. Some of the most challenging issues in this scenario are the enforcement of authorization policies and the policies update for secure data retrieval.
