Decentralised Disruption Tolerant military Network

Disruption Tolerant Network technologies allow wireless devices carried by soldiers in military networks and access the confidential information by storage nodes. Data to be stored and retrieved from storage nodes, since the data handled by the soldiers are different, it is necessary to implement the security policy and access control policy to them. The authorization policies and secure data retrieval by soldiers are the key issues in DTN. Ciphertext Policy Attribute Based Encryption is a cryptographic resolution to the access control issues and fulfills the necessities for secure text retrieval in DTNs. To transmitting the secret image in DTN, Visual Cryptography Schemes are used. These schemes are used to hide the secret information in images. To support both text and image retrieval in DTN, the proposed algorithm can be enhanced. However, previous approach suffers attribute revocation problem in information, pixel expansion and noise problem in images. The proposed system provides secured retrieval of text and image, using Multiauthority CP-ABE with Data Revocation and customized GAS algorithm for decentralized disruption tolerant military network respectively. On demonstrating the proposed system, the private information is secured and efficiently managed in Disruption Tolerant Military Network.
