Mobile nodes in military environments such as a battlefield or a hostile region suffer from intermittent network connections and frequent partitions. Disruption-Tolerant Network (DTN) technologies are best solutions that allow wireless devices carried by soldiers to communicate and access the confidential information or command reliably by exploiting external nodes. Cipher text-Policy Attribute-Based Encryption (CP-ABE) is a cryptographic solution to the access control issues. The problem of applying CP-ABE in decentralized DTNs generates several security and privacy issues with attribute updation, key escrow problem and attributes coordination issued from different key authorities.
