DEPRECATED: Covert Timing Channel

This CWE entry was consolidated into CWE-385 to improve the taxonomy and eliminate redundancy. The concept of a 'Covert Timing Channel' describes a side-channel attack where an attacker infers sensitive information by measuring how long specific operations take to execute, rather than by directly accessing the data itself. These attacks exploit subtle timing differences in code paths, cache hits/misses, or branch predictions. Developers should consult CWE-385 for guidance on identifying and mitigating these vulnerabilities. Defenses typically involve eliminating data-dependent timing variations through constant-time algorithms, cryptographic blinding, or adding random delays to obscure measurable differences. Understanding this attack vector is crucial for securing cryptographic implementations and other sensitive logic.
