Abstract (Summary)

The current project presents a secure data retrieval system that can be used for accessing confidential information in decentralized disruption-tolerant networks. Major challenges include the authorization policies to be enforced, and the updating of policies for data retrieval. A promising cryptographic approach for issues involving access control is the use of cipher text-policy attribute-based encryption (CP-ABE). However, the problem of applying CP-ABE in these networks is that it creates security and privacy concerns regarding the key escrow. The project simulates a secure data retrieval system using CP-ABE and it successfully transmits classified information to the recipient while providing an advanced structure for remote networks. Collusion-resistance blocks unauthorized access to data. The key escrow problem is resolved and an immediate attribute revocation technique enhances backward/forward secrecy of confidential data further reducing the windows of vulnerability.
