Evolution of Embedded Platform Security Technologies: Past, Present & Future Challenges

In recent years, the proliferation of intelligent embedded technologies is opening venues to new service and computing models, providing diverse socio-economic benefits. These intelligent technologies are giving rise to a wide range of public and private applications by sharing and analysing generated data. This includes smart home, smart health, smart city, autonomous vehicles, smart grid and smart manufacturing etc. However, where this sharing of data brings benefits and opportunities, it simultaneously presents security risks and challenges. The realisation and prototyping of such technologies require a computing hardware widely available in the form of an embedded platform. The security perimeter and the attack surface of these platforms rely on their supported security and defence mechanisms. This paper aims to build a body-of-knowledge in this area for the security research community. It present the state-of-the-art security frameworks and architectures, discuss architectural shortcomings and root-causes of leading security technologies rather than discussing vulnerabilities and attacks. The paper concludes advocating secure-by-design platform approach and classifying platform security methods to realise robust embedded platform security architecture.
