Integration of Monitoring Mechanisms in Secure Network Interfaces for Peripherals to Protect IO Communication in NoC-based Many-cores

Many-core systems have gained popularity due to their high performance and parallelism. However, they also present significant security challenges. One critical issue that remains insufficiently addressed in current research is protecting Input/Output (IO) communication within these systems. This paper proposes a Secure Network Interface with Peripherals (SNIP) design, incorporating security mechanisms to safeguard communication between internal components in many-core systems. The proposed SNIP makes an original contribution by integrating security features into its network interface design, thereby addressing a research gap in the communication between many-core systems and peripherals. Furthermore, the paper proposes a monitoring mechanism within the SNIP to detect suspicious behavior during IO communication. The SNIP design focuses on the trade-offs between security, performance, and area overheads. Results demonstrate that the SNIP effectively protects IO communication in many-core systems from potential attacks while imposing minimal overhead, and it enables system-level countermeasures through the monitoring information provided. The proposed SNIP design offers a promising solution to address the security challenges of many-core systems, particularly in safeguarding IO communication.
