Detect timing side-channel vulnerabilities by analyzing cryptographic implementations for execution time differences correlated with secret data. This Skill identifies code paths or operations whose execution time depends on sensitive information, helping prevent data leakage.

Dudect is a statistical analysis tool used to find timing leaks by measuring execution time variations correlated with secret data. It provides quick-start examples to statistically analyze cryptographic functions and identify operations that leak sensitive information.

Use timecop for dynamic tracing to pinpoint secret-dependent operations in code. It works alongside dudect's statistical analysis to identify exact code paths where execution time depends on sensitive data, enabling precise vulnerability detection in cryptographic primitives.

Yes, you can audit encryption libraries for timing attacks without external dependencies. This Skill provides scripts and references to run dudect and timecop, ensuring operations involving private keys do not leak information through timing differences during cryptographic implementation analysis.

Test cryptographic primitives for timing attacks when auditing new encryption libraries, implementing protocols, or handling sensitive data. Timing side-channel vulnerabilities can leak private keys and secret information through execution time variations, making detection critical before deployment.
