Secured Data Retrieval System in Unfriendly Regions Using CP-ABE Based in Ad Hoc Disruption- Tolerant Networks

K Yamini, V Jhansi Lakshmi


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. 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 battle field; this provides them to communicate effectively and share the information confidently. 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. 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. We analyzed the proposed mechanism and applied to the disruption-tolerant military network to access the information securely.
