AI Technical Summary
The modular architecture of existing security chip fault injection devices results in long signal paths, complex system integration, difficulty in achieving high-precision attacks, limited communication protocol support, signal acquisition modules that cannot meet the requirements for high-frequency electromagnetic leakage capture, and low stability and signal-to-noise ratio of the test system, leading to insufficient attack success rate.
The high-precision voltage injection module, clock injection module, multi-protocol communication parsing module, and dual-channel signal acquisition module are integrated into a single device. The timing synchronization of each module is coordinated by the FPGA main control unit. The standardized interface design supports multi-point power supply and high current transmission. The protocol content parsing trigger engine generates accurate trigger signals. Combined with gigabit network port and PoE power supply solution, high-speed host computer communication and local display are realized.
It significantly improves the accuracy and success rate of security hardware fault injection, realizes the integration of attack, collection and analysis, reduces equipment size and cost, and improves deployment efficiency and signal stability.
