SNAP: An architecture for secure medical sensor networks


We identify the security threats facing a sensor network for wireless medical monitoring, and we propose a public-key architecture using elliptic curve cryptography to address these issues. We also present a preliminary protocol for securely establishing pairwise symmetric keys between a sensor and a base station using ECC. To evaluate our protocol, we are working on an implementation of ECC for the Moteiv Tmote Sky platform. Our initial release performs competitively with existing implementations for the Crossbow MICA. © 2006 IEEE.
