Abstract
In real-time mission critical sensor applications, authentication of peer motes becomes consequential. What makes it more interesting is, compared with data integrity and source authenticity, information confidentiality can be less important in many situations. The Dirty Bomb Detection and Localization scenario is one such application. The authenticity and integrity of messages received by base station greatly influence final tracking results. We hence propose the group-based peer authentication for sensor nodes. The security component (MultiMAC) we provided uses the SkipJack implementation in TinySec as symmetric cipher. Each sensor stores a different set of keys in its ROM which is pre-defined by a key mapping scheme. Multiple message authentication code (MAC)s of every message are calculated in SkipJack, using the key set assigned to the sensor node. The receiver authenticates the message by recomputing MACs using its common keys with the sender. Our scheme fits contingent real-time constraints of the application and can be adapted for other occasions as well.
