Side channel parameter characteristics of code injection attacks

Abstract

Embedded systems are suggestive targets for code injection attacks in the recent years. Software protection mechanisms, and in general computers, are not usually applicable in embedded systems since they have limited resources like memory and process power. In this paper we investigate side channel characteristics of embedded systems and their applicability in code injection attack detection. The architectural simulation for execution time, power usage and temperature on benchmarks shows that these parameters disclose meaningful and distinguishable behaviours in case of attack.
