Weakness (CWE)

CWE-1247: Improper Protection Against Voltage and Clock Glitches

Base

The device does not contain or contains incorrectly implemented circuitry or sensors to detect and mitigate voltage and clock glitches and protect sensitive information or software contained on the device.

How to prevent it (1 mitigation)

  1. Architecture and Design, Implementation

    A device needs to guard against fault attacks such as voltage glitches and clock glitches that an attacker may employ in an attempt to compromise the system. At the circuit-level, using Tunable Replica Circuits (TRCs) or special flip-flops such as Razor flip-flops helps mitigate glitch attacks. Working at the SoC or platform base, level sensors may be implemented to detect glitches. Implementing redundancy in security-sensitive code (e.g., where checks are performed)also can help with mitigation of glitch attacks.
