Security strategies in embedded systems

Okereke G. E and Oluoha Onyekwere U

Embedded systems are a unique set of computing devices, with unique characteristics, which in turn gives rise to unique and interesting vulnerabilities. These vulnerabilities have become even more evident with the ever increasing rise in the use of embedded systems and the advent of the Internet of Things (IoT). The ever increasing cases of information security breaches necessitates the pressing need for greater and more comprehensive security measures for embedded systems. Unlike in general Information Security, where security is considered as the implementation of a hardware cryptographic algorithms and/or security protocols, embedded systems present a totally different set of metric which must be considered throughout the design process (from design conception to end of life and disposal). In other to ensure a more reliable and resilient security solution, these new metrics must be considered side-by-side other important metrics including cost, performance, and power.
This paper closely peruses the unique characteristics of embedded systems, establishing major challenges encountered in embedded system architecture design, and surveys solution techniques in current literature and emerging research proposed to address these unique challenges.
