Abstract

Sleep deprivation attacks are a form of denial ofservice attack whereby an attacker renders apervasive computing device inoperable by draining thebattery more quickly than it would be drained undernormal usage. We describe three main methods for anattacker to drain the battery: (1) Service requestpower attacks, where repeated requests are made tothe victim for services, typically over a network--evenif the service is not provided the victim must expendenergy deciding whether or not to honor the request;(2) benign power attacks, where the victim is made toexecute a valid but energy-hungry task repeatedly, and(3) malignant power attacks, where the attackermodifies or creates an executable to make the systemconsume more energy than it would otherwise. Ourinitial results demonstrate the increased powerconsumption due to these attacks, which we believeare the first real examples of these attacks to appear inthe literature. We also propose a power-securearchitecture to thwart these power attacks byemploying multi-level authentication and energysignatures.
