Multi-Processor Systems on Chips (MPSoCs) have emerged as key components in a wide range of computing systems, from wearable devices to high-performance computing at the Edge. With the ever-increasing application of such products in various aspects of human lives, ensuring the security and reliability of MPSoCs has become paramount. Security concerns in MPSoCs encompass a broad spectrum of threats, including hardware Trojans, side-channel attacks, and malicious firmware injections. These vulnerabilities pose significant risks, ranging from data breaches to system downtime, compromising both the confidentiality and integrity of sensitive information processed within the system. Concurrently, reliability challenges, such as aging effects, manufacturing defects, and thermal issues, can lead to performance degradation and system failures over time. Effective mitigation strategies require a holistic approach that integrates security and reliability considerations throughout the design, verification, and deployment phases of MPSoCs. This presentation, derived from the continuous research of Dr. Ahmad Patooghy in the field since 2010, explores how security and reliability of MPSoCs might be related under various models of threats. The presentation classifies the explored threat models into three different classes: 1) threat models with no relation between security and reliability, 2) threat models with a direct relation between security and reliability, and 3) threat models with an inverse relation between security and reliability.
