Mobile nodes in challenging network scenarios such as military networks are likely suffer from intermittent network connectivity i.e., the signals are stopping and starting at regular intervals. Disruption-Tolerant Network (DTN) technology is used to overcome this problem. It allows accessing the wireless devices and confidential information reliably. The confidential information must be securely retrieved. The key issues are enforcement of authorization policies update for secure data retrieval. The Cipher text Policy Attribute-Based Encryption (CP-ABE) is the best solution to the access control issues. Privacy and security challenges which include key escrow, attribute revocation can be resolved by using CP-ABE.
