Secure Military Communication Using Ciphertext Policy Attribute Based Encryption for Decentralized DTN

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. Disruption-tolerant network (DTN) innovations are getting to be fruitful results that permit remote device conveyed by officers to speak with one another and access the confidential data or secret data or summon dependably by abusing outside capacity nodes or storage nodes. Thus a new methodology is introduced to provide successful communication between each other as well as access the confidential information provided by some major authorities like commander or other superiors. The methodology is called Disruption-Tolerant Network (DTN). This system provides efficient scenario for authorization policies and the policies update for secure data retrieval in most challenging cases. The most promising cryptographic solution is introduced to control the access issues called Cipher text Policy Attribute Based Encryption (CP-ABE). Some of the most challenging issues in this scenario are the enforcement of authorization policies and the policies update for secure data retrieval. Ciphertext -policy attribute-based encryption (CP-ABE) is a guaranteeing cryptographic answer for the right to gain entrance control issues. 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.
