AbstractIn recent years, Network-on-Chip (NoC) has gained increasing popularity as a promising solution for the challenging interconnection problem in multi-processor systems-on-chip (MPSoCs). However, the interest of adversaries to compromise such systems grew accordingly, mandating the integration of security measures into NoC designs. Within this paper, we introduce three novel lightweight approaches for securing communication in NoCs. The suggested solutions combine encryption, authentication, and network coding in order to ensure confidentiality, integrity, and robustness. With performance being critical in NoC environments, our solutions particularly emphasize low latencies and low chip area. Our approaches were evaluated through extensive software simulations. The results have shown that the performance degradation induced by the protection measures is clearly outweighed by the aforementioned benefits. Furthermore, the area overhead implied by the additional components is reasonably low.
