As electronic systems are pervading our lives, MPSoC (multiprocessor system-on-chip) security is becoming an important requirement. MPSoCs integrate several computation components linked through a communication structure. MPSoCs are able to support multiple applications on the same chip. Such flexibility also represents vulnerability. The challenge is to provide MPSoC security that makes possible a trustworthy system that meets the performance and security requirements of all the applications. MPSoC can be attacked via hardware/software. Software attacks are responsible for 80% of the security incidents. All software attacks start with an abnormal communication. The aim of the presentation is to show how the MPSoC communication structure can be used to protect the system.
Network-on-Chip (NoC) is employed to support the MPSoC high communication requirements. A NoC is an integrated network that uses routers to allow the communication among the computation structure components. The NoC may contribute to the overall security of the system, providing the ideal mean for monitoring systems behavior and detecting specific attacks. NoC is able to integrate agile and dynamic security firewalls to detect attacks based on different security rules. This approach takes advantage of the NoC wide system visibility and critical role in enabling system operation, exploiting the NoC components to detect and prevent a wide range of attacks. In the talk it will be presented the results of adopting different levels of MPSoC protection at NoC design. The results were obtained through a SystemC-TLM timed simulation framework. It automatically carries out performance evaluations for a wide variety of MPSoC scenarios. It will be shown that NoC security can perform a fast detection of a wide range of attacks. Penalties due to the integration of NoC security are limited to a fraction of time and space of the system.
