This achievement marks a significant step toward the day when classical encryption methods might no longer provide sufficient protection. SPN algorithms are essential for the security of critical systems across various industries. The study, titled Quantum Annealing Public Key Cryptographic Attack Algorithm Based on D-Wave Advantage, outlines two approaches using quantum annealing to target RSA security:
- The first method relies solely on the D-Wave quantum computer, which tackles an optimization problem within an exponentially large space.
- The second method combines classical cryptography with quantum annealing algorithms.
Although Wang declined to share further details due to the sensitive nature of the topic, the findings suggest that algorithms like AES-256 could be more vulnerable than previously thought.
This discovery highlights the pressing need for the development of post-quantum cryptographic algorithms. The U.S. National Institute of Standards and Technology (NIST) is currently working on setting new standards that can withstand attacks from future quantum computers. As the era of quantum computing approaches, the landscape of cybersecurity is poised for a dramatic transformation.
