Abstract -
Mobile nodes in military environments such as a
battlefield or a hostile region are likely to suffer from intermittent
network connectivity and frequent partitions. Disruption-tolerant
network (DTN) technologies are becoming successful solutions that
allow wireless devices carried by soldiers to communicate with each
other and access the confidential information or command reliably
by exploiting external storage nodes. Some of the most challenging
issues in this scenario are the enforcement of authorization policies
and the policies update for secure data retrieval. Cipher text-policy
attribute-based encryption (CP-ABE) is a promising cryptographic
solution to the access control issues. However, the problem of
applying CP-ABE in decentralized DTNs introduces several security
and privacy challenges with regard to the attribute revocation, key
escrow, and coordination of attributes issued from different
authorities. In this paper, we propose a secure data retrieval scheme
using CP-ABE for decentralized DTNs where multiple key authorities
manage their attributes independently. We demonstrate how to apply
the proposed mechanism to securely and efficiently manage the
confidential data distributed in the disruption-tolerant military
network.
