Abstract: Existing code update protocols target efficiency and assume correct behavior from participating sensor nodes. This work aims for the progressive, resource sensitive verification of code updates in sensor networks to ensure that unauthorized updates from malicious nodes are not propagated, while correct updates continue to be efficiently disseminated.
