Strengthening NoC Security: Leveraging Hybrid Encryption for Data Packet Protection

The increasing complexity and scale of modern computing systems have led to the emergence of System-on-Chip (SoC) architectures, with Network-on-Chip (NoC) architectures serving as a communication infrastructure within these systems. Due to rigid time-to-market constraints, recent SoC designs involve using third-party IPs. This outsourcing can lead to security vulnerabilities in SoC, especially in N oC packet transmission. Considering security attacks, this paper addresses the need for cost-effective secure packet transmission in N oC. We propose a hybrid encryption framework by discussing the challenges associated with symmetric and asymmetric encryption techniques to achieve a balance between security and efficient data transmission in NoC. By combining the strengths of both encryption methods, our approach aims to provide enhanced protection against security threats while minimizing performance overhead.
