Privacy Protection for decentralized data in military network using CP-ABE

Abstract

Wireless sensor networks will be widely used to focused on making these networks feasible and useful, security has received little attention. We present a suite of security protocols optimized for sensor networks: SPINS.SPINS has two secure building blocks: SNEP and TESLA. SNEP includes: data confidentiality, two-party data authentication, and evidence of data freshness. TESLA provides authenticated broadcast for severely resource-constrained environments. We implemented the above protocols, and show that they are practical even on minimal hard ware: the performance of the protocol suite easily matches the data rate of our network. Additionally, we demonstrate that the suite can be used for build ing higher level protocols.
