Security and Trustworthy Embedded Systems

Abstract

Embedded systems are increasingly becoming the backbone of modern digital infrastructure, ranging from medical devices and automotive systems to industrial control and IoT devices. With this pervasive integration, security and trustworthiness have emerged as crucial concerns, as attacks on embedded devices can have severe consequences, including financial loss, privacy breaches, and even threats to human safety. This paper provides a comprehensive review of the security challenges faced by embedded systems, the threats targeting them, and strategies for ensuring trustworthiness. It discusses hardware-based, software-based, and hybrid security mechanisms, including encryption, secure boot, hardware root-of-trust, and intrusion detection systems. Additionally, the paper examines evaluation metrics for trustworthy systems, challenges in real-time embedded environments, and emerging trends such as blockchain integration and AI-based anomaly detection. The aim is to provide a roadmap for designing resilient and reliable embedded systems for diverse applications.

KEYWORDS: Embedded systems, security, trustworthiness, IoT, secure boot, hardware root-of-trust, intrusion detection, and encryption.
