Intermittent network connectivity and node partitions are frequently occur in military environments like battlefields and some hostile regions. Disruption-tolerant network (DTN) technologies are allows wireless devices to communicate with each other and access the confidential information in military applications by exploiting external storage nodes. The secure data retrieval scheme using Revocable Multi authority CP-ABE for decentralized DTNs where multiple key authorities manage their attributes independently. Some of the most challenging issues in this scenario are the enforcement of authorization policies and the policies update for secure text and video retrieval. Cipher text-policy attribute-based encryption (CP-ABE) is a promising cryptographic solution to the access control issues The Multi authority CP-ABE and AES algorithm it provides secure retrieval of text and video respectively. The proposed system provides secure retrieval of text and video, using modified CP-ABE and AES algorithm for decentralized DTNs respectively. Also, demonstrating how to apply the proposed mechanism to securely and efficiently manage the confidential information distributed in the disruption-tolerant military network. It implemented using Network Simulator-2.
