芯片安全IP: Digital Sensor Secure-IC Security IP Cores: Digital Sensor 为了防护故障注入，传统的防护方式是一一针对的在芯片上布置模拟传感器，但是模拟传感器体积大功耗大成本高等确定日益成为掣肘，针对这一难点，Secure-IC设计了数字传感器（Digital Sensor），以数字电路实现传感器功效，防御一切故障注入，可防御现有的故障注入方式（包括电压、时钟、激光、电磁、温度等）以及未来可能出现的故障注入方式。 Digital Sensor Anti Fault Injection Attacks, All-in-one Fault Injection Detector, Entirely Digital. 1. PROBLEM SOLVED In cryptography, an attack can be performed by injecting one or several faults into a device thus disrupting the functional behavior of the device. Techniques commonly used to inject faults consist in introducing variations in the source voltage, clock frequency, temperature, or irradiating with a laser beam etc. Unlike analog sensors which are dedicated to the detection of a specific perturbation attack, the Digital Sensor is designed to detect various threats belonging to the family of Fault Injection Attacks (FIA): • Input clock frequency (clock glitches, Overclocking): reduction of the clock period to provoke a critical path violation. • Input voltage (power glitches, underfeeding): reduction of supply voltage to increase the propagation delay of combinational logic. • Temperature (heating): modification of the temperature to increase the propagation delay. • Radiations (laser spot, light spot, Electromagnetic): provoke bit set or reset in registers by irradiation. 2. OVERVIEW • Fully digital and based on the standard cells of library design kit • Transferable to any design kit • Lightweight • Difficult to identify by an attacker (melted within the rest of design) • Customizable sensitivity • Compatible with clock gating feature • Several sensors can be regrouped around a unique bus interface. • Real-time hardware alarm • No calibration after design Digital Sensor converts all monitored stresses into a timing stress which is then measured. When a threat is detected, it provides the system with a measurement of the threat’s level and it raises the hardware alarm.
