Hardware-Based Security for Embedded Systems: It is protection against modern threats

Abstract

Our daily lives are becoming increasingly reliant on embedded systems, for which advancements in technology seem to progress with a degree of 'news almost every day'. Regardless of whether this computer system is in smartphones and smart home devices or in industrial control systems and automotive electronics this computer system is everywhere. However, as they become more comfortable with the current, more and more demands are being requested from robust security measures to protect against evolving cyber threats.The past decade has seen dramatic changes in what is involved in building a secure embedded systems. Embedded devices were deployed pretty much in isolation and thus had little interaction with other devices, and consequently, were not in the line of fire for external threats. Until the advent of the Internet of Things (IoT), this paradigm remained the status quo, but that has completely changed. Today's embedded systems are located in communication with large numbers of other devices, not only are interconnect, but they share data. This new connectivity greatly enhanced functionality (because the networking had been much improved), but it also presented new ways to attack.
