    "summary": "SentryBus maps where I2C manipulation may remain observable—and where a host-side monitor loses the ability to distinguish it.",
    "body_text": "The proposed monitor uses transaction timing, read and write sequences, transfer lengths, address behavior and raw-data transitions from the host-facing sensor bus. A dual-sided testbed established timing and capture limits, including a low-cost analyzer that could silently truncate data. Controlled attack trials are still outstanding and the authors claim no detection rate, making the negative boundary result as important as the proposed feature set.",
