Secure Communication using CP-ABE for Disruption Tolerant Sensor Network

Disruption-Tolerant sensor Networks(DTSN) deliver data to the collection of intermittently connected nodes. In traditional networks, Intruder nodes within DTSN may try to attempt data destruction in transmits the data to its destination. Disruption-tolerant sensor network (DTSN) technologies are becoming successful solutions that allow wireless devices to communicate with each other and access the confidential information reliably by exploiting external storage nodes by using a prims routing algorithm to find shortest path from source and destination. Some of the most challenging issues in this scenario are the enforcement of authorization policies and the policies update for secure data communication. Cipher text-policy attribute-based encryption (CP-ABE) is a promising cryptographic solution to the access control issues. However, the problem of applying CP-ABE DTSN introduces several security and privacy challenges with regard to the attribute revocation, key escrow, and coordination of attributes issued from different authorities. Here the proposed secure data communication using CP-ABE for DTSN where key authorities manage their attributes independently and also demonstrate to apply the proposed mechanism to securely and efficiently manage the confidential data distributed in the disruption-tolerant sensor network for energy efficiency.
