Abstract :

Mobile nodes in military network scenarios carried by soldiers may be temporarily disconnected due to jamming and environmental factors. Disruption-tolerant network (DTN) technologies provide storage nodes to store the messages when there is no end-to-end connection. Attribute-based-encryption (ABE) is an approach that enables an access control over encrypted data using access policies and attributes, but this introduces several security and privacy challenges. Here we propose a secure data retrieval scheme using Cipher-text-policy ABE for decentralized DTNs that provides a scalable way of encrypting data. The proposed scheme features immediate attribute revocation, provides fine-grained access policy and resolves key escrow problem.
