Abstract:We present a mechanism for securing group communications in Wireless Sensor Networks (WSN). First, we derive an extension of Logical Key Hierarchy (LKH). Then we merge the extension with Directed Diffusion (DD). The resulting protocol, LKHW, combines the advantages of both LKH and DD. In particular, LKHW enforces both backward and forward secrecy, while incurring only limited overhead in terms of the number of messages required. This is the first security protocol that leverages DD, and it shows that such a paradigm is also viable for other applications than routing. Finally, a few new research directions that originate from this paper are discussed.
