What’s New ? Wireless medium is easy to snoop on Due to ad hoc connectivity and mobility, it is hard to guarantee access to any particular node (for instance, to obtain a secret key) Easier for trouble-makers to insert themselves into a mobile ad hoc network (as compared to a wired network) 398
Resurrecting Duckling [Stajano99] Battery exhaustion threat: A malicious node may interact with a mobile node often with the goal of draining the mobile node’s battery Authenticity: Who can a node talk to safely? Resurrecting duckling: Analogy based on a duckling and its mother. Apparently, a duckling assumes that the first object it hears is the mother A mobile device will trust first device which sends a secret key 399
