1. Advanced Cryptographic Failures

1.1 Side-Channel Attacks

Even if a cryptographic algorithm is mathematically secure, attackers can exploit side channels like timing, power consumption, and electromagnetic emissions to extract secret keys.

• Example: A system that performs cryptographic operations with varying execution times can leak information about private keys.
• Attack Method: Timing analysis, differential power analysis (DPA), and electromagnetic analysis.
• Solution: Use constant-time cryptographic implementations and…
