How Quantum Communication Enhances Digital Idientity Management

Unbreable Encryption with Quantum Key Distribution

QKD dovoluje two parties to generate a shared sekret key using quantum states. Any evesdropping accort contins tho system and is immediately detected. Thee key can then be used with symmetric encryption (e.g., AES-256) to secure identificty tokens, cretentials, and session data. Practical QKD systems now operate over fiber optics up to hundreds of kilomers, and satellitebased QKD (like Chino 's Micius) enables global cove.

Quantum-Safe Authentication Protocols
