Abstract

In today’s world of growing commercial environment, transmitting secure data has become a great challenge. Portable nodes in military environments are prone to experience irregular system network and frequent partitions. A methodology called Disruption-tolerant network (DTN) permits remote devices to speak with one another and access the confidential data or secret data by abusing outside capacity nodes or storage nodes. This system provides efficient scenario for authorization policies and policies update for secure data retrieval. One of the most promising cryptographic solutions introduced to control the access issues is Cipher text Policy Attribute Based Encryption (CP-ABE). However, the problem of applying CP-ABE in decentralized DTNs introduces several security and privacy challenges with regard to the attribute revocation, key escrow, and coordination of attributes issued from different authorities. In this paper, we propose a secure data retrieval scheme using CP-ABE for decentralized DTNs where multiple key authorities manage their attributes independently. We demonstrate how to apply the proposed mechanism to safely and proficiently deal with the classified information dispersed in the Interruption or disruption tolerant network.
