Secure and Efficient Confidential Data Using Multiple Authorities in DTN

for secure data retrieval in decentralized Disruption Tolerant Networks (DTNs). Here we are design multiple key authorities manage their attributes. Immediate attribute revocation enhances security in storage nodes. Key escrow problem is resolved by an escrow-free key issuing protocol that exploits the characteristic of the decentralized Disruption Tolerant Networks architecture proposed a decentralized approach. Previous techniques are not verifying the users effectively. Demonstrate how to apply the proposed mechanism to securely and efficiently manage the confidential data distributed in the disruption-tolerant military network. Here we are design coordinates attributes verification after submission of each and every user. Finally the Disruption-tolerant network (DTN) technologies are provide the 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
