Fault Injection in On-Chip Interconnects: A Comparative Study of Wishbone, AXI-Lite, and AXI
Fault injection attacks exploit physical disturbances to compromise the functionality and security of integrated circuits. As System on Chip (SoC) architectures grow in complexity, the vulnerability of on chip communication fabrics has become increasingly prominent. Buses, serving as interconnects among various IP cores, represent potential vectors for fault-based exploitation. In this study, we perform simulation-driven fault injection across three mainstream bus protocols Wishbone, AXI Lite, …

Ultrafast optical gating in a nonlinear lithium niobate microcavity
Recent advances in optical simulation and computational techniques have renewed interest in high-finesse optical cavities for applications such as enhancing light-matter interactions, engineering complex photonic band structures, and storing quantum information. However, the extended interaction times enabled by these cavities often come at the cost of slow optical read-out protocols and limited control over system transients. To address this challenge, we demonstrate an ultrafast intra-cavity …
