code injection

Embedded systems are becoming a suggestive target for Code Injection attacks in recent years. Software protection mechanisms in general computers are not usually applicable in embedded systems as they come with limited resources like memory and processor. In this paper we investigate side channel characteristics of embedded systems and their usability in code injection attack detection. The architectural simulation for execution time, power usage and temperature on benchmarks shows that these parameters would disclose meaningful and distinguishable behavior in case of attack.
