: The "Key Exchange" problem—how do you share the key securely? 2. Asymmetric (Public-Key) Cryptography
: Unlike RSA, which quantum computers could easily break, code-based cryptography is currently considered "quantum-resistant." 🔐 Why This Matters Today
: Proves that a message was sent by a specific person and hasn't been altered. Coding Theory: Reliability in the Noise
This uses a pair of keys: a (shared with everyone) and a Private Key (kept secret).
