Overview:
Due to the ever-increasing design complexity and physical constraint in frequency scaling, chip multiprocessors are considered the de facto architecture baseline for future processor generation. Through resource sharing, applications running on a CMP can achieve better resource utilization and faster inter-core communication, leading to a higher overall throughput for the entire system. From a different perspective, however, such architectures are also more susceptible to Denial-of-Service (DoS) attacks on these shared resources, increasing the vulnerability in performance. Furthermore, as the number of cores increases, attacks similar to Distributed Denial-of-Service (DDoS) attacks on the Internet can be employed to throttle these on-chip resources with the presence of multiple malicious applications.
