The Cipher text-policy Attribute Based Encryption (ABE) for secure data retrieval in decentralized Disruption Tolerant Networks (DTNs) where multiple key authorities manage their attributes independently. Immediate attribute revocation enhances backward/forward secrecy of confidential data by reducing the windows of vulnerability. Key escrow problem is resolved by an escrow-free key issuing protocol that exploits the characteristic of the decentralized DTNs architecture proposed a decentralized approach; their technique does not authenticate users. Demonstrate how to apply the proposed mechanism to securely and efficiently manage the confidential data distributed in the disruption-tolerant military network.
