Frequent partitions and stopping network connectivity hampers the mobile nodes, e.g. in military areas. DTN's (Disruption Tolerance Networks) like technologies are found to be emerging as successful solutions for wireless devices which are carried by soldiers. Here by exploiting external storage nodes, these devices are used for communicating with each other and access the secret information. Limitations are enforcement of policies authorization and policies update for safe data retrieval. To handle control issues CP-ABE (Ciphertext-Policy Attribute-Based Encryption) is promising cryptographic solution.
