Abstract—Generally the Military environments like battlefield and hostile networks operate in ad hoc mode and they are vulnerable to isolated network connectivity. Deployment of Disruption-tolerant networks (DTN) enhances the connectivity between wireless devices carried by soldiers in battle field; this provides them to communicate effectively and share the information confidently. The major research issue is to achieve effective and secure communication in Delay-Tolerant Networks by implementing authorization policies and the policies update for secure data collection. Cipertext-policy attribute based encryption (CP-ABE) is effective cryptographic technique to access control issues. Ad hoc network are decentralized and resource constrained networks, applying CP-ABE to such networks is a challenging issue, in turn it introduces new security and privacy issues related to attribute revocation, coordination of attributes, and key escrow. This paper mainly focus on a secure data collection mechanism using CP-ABE for ad hoc DTNs where more than one key authority manages their attributes dynamically and independently. We analyzed the proposed mechanism and applied to the disruption-tolerant military network to access the information securely.
