Quantum Computing: Implications for Future Cybersecurity
Quantum computing represents both a significant threat to current cybersecurity practices and an opportunity for revolutionary advances in secure communication.
The Quantum Threat
Quantum computers will be capable of breaking many of the cryptographic algorithms that currently protect our digital communications and data.
RSA, ECC, and other public-key cryptosystems that rely on the difficulty of factoring large numbers will become vulnerable to quantum attacks.
Post-Quantum Cryptography
Researchers are developing new cryptographic algorithms that will remain secure even against quantum computers.
These quantum-resistant algorithms are based on mathematical problems that are believed to be difficult for both classical and quantum computers to solve.
Quantum Key Distribution
Quantum mechanics also offers new possibilities for secure communication through quantum key distribution (QKD).
QKD provides theoretically unbreakable communication security based on the fundamental principles of quantum physics.
