Shaik Meeravali, Harwant Singh Arri · 2015
Abstract−The Military environments like battlefield and hostile networks operate in ad hoc mode and they suffer isolated network connectivity. Deployment of Disruption-tolerant networks (DTN) enhances the connectivity between wireless devices carried by soldiers in battlefield, 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 focuses 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.
