Editing Symmetric Cryptography (section)

Future Frontiers: (1) **Lightweight Cryptography**: Designing AES-like security for tiny "Internet of Things" (IoT) sensors that have almost no power. (2) **Authenticated Encryption (AEAD)**: Ciphers that not only hide the message but also prove that the message hasn't been "tampered with" by a hacker. (3) **Hardware Acceleration**: Building special "AES-NI" circuits directly into every computer CPU to make encryption "cost zero" in terms of speed. (4) **Quantum-Resistant Symmetric Keys**: While quantum computers can't "break" AES, they make it 2x weaker. The future simply involves moving from 128-bit to 256-bit keys to stay safe forever.
