Broadcast Secrecy Via Key-Chain Based Encryption in Single-Hop Wireless Sensor Networks

Broadcast is used in wireless sensor networks for operations such as software updates, network queries, and command dissemination. Though authentication of broadcast messages is probably the most critical primitive, certain applications such as battlefield control and natural resource management also require the broadcast data to be kept secret from eavesdroppers. In this paper, the authors design, implement, and evaluate a novel scheme that meets the requirements of secrecy, authenticity, integrity, and freshness of broadcast messages in the context of a single-hop wireless sensor network.
