Quantum Cryptography
Protecting data in the quantum era: How quantum principles ensure unbreakable security.
Jump to SolutionsWhy Quantum Cryptography Matters
Quantum computing threatens traditional encryption methods like RSA and AES. Quantum cryptography leverages the laws of physics to create theoretically unbreakable security, ensuring data remains protected against both classical and quantum attacks.
Threat Landscape
2048-bit RSA keys can be cracked in seconds by quantum computers using Shor's algorithm.
Quantum-Safe Future
Post-quantum algorithms and quantum key distribution create security that even quantum computers cannot break.
Key Technologies
Quantum Key Distribution (QKD)
Uses quantum entanglement to securely exchange encryption keys with perfect forward secrecy.
Lattice-Based Crypto
Mathematical problems resistant to both classical and quantum attacks vectors.
Hash-Based Signatures
Post-quantum digital signature schemes using cryptographic hash functions.
