When encryption works perfectly and still fails

a year ago

Encryption is fundamental for secure communication but has inherent vulnerabilities beyond mathematical strength.
Publicly discussed cryptography threats include breakthroughs in mathematical problems (e.g., P = NP, quantum computing), cryptanalysis (e.g., Enigma machine), and side-channel attacks (e.g., Spectre, Meltdown, Rowhammer).
The most significant threat is human error, such as adding the wrong person to a group chat, bypassing encryption security.
Example: National Security Advisor Mike Waltz accidentally added a journalist to a sensitive Signal group chat, exposing classified information.
Key management is a critical and often overlooked challenge in cryptography, harder than the encryption itself (Kissner’s law).
Key management issues include identity verification, key generation authority, and key revocation/rotation.
Many breaches stem from key management failures (e.g., phishing) rather than cryptographic weaknesses.
Key management lacks standardized solutions and heavily depends on application-specific user experience.
