Abstract
In heterogeneous three-dimensional Network-on-Chip (3-D NoC) systems, security threats arise from malicious nodes in untrusted dies that disrupt data flow and leak proprietary information. To mitigate such risks, a security-aware priority-based packet routing algorithm is proposed. The developed routing methodology prioritizes routing security sensitive data packets through trusted dies. The algorithm dynamically computes a cost metric that accounts for router utilization, distance between the source and destination nodes, directions of traversal, and packet priority, and determines whether data is routed via a slower but secure path or a faster yet compromised path. High-priority packets are reliably delivered, while low-priority packets that tolerate delay traverse untrusted dies. When high-priority packets are sparse and the untrusted die is placed as the middle plane of a three-tier 3-D IC stack, the algorithm reduces high-priority packet hops in the untrusted die by approximately
, averaged across flit sizes and packet generation rates, while the increase in average packet latency and dynamic power consumption is
and
, respectively. Running t-tests to compare ZXYZ routing and the proposed routing algorithm yield p-values of 0.3347 and 0.6322 for average packet latency and dynamic power consumption, respectively, which indicates no significant difference in performance and power consumption.
