Chinese researchers break RSA encryption with a quantum computer

In a groundbreaking development that could redefine global cybersecurity, a team of Chinese researchers has successfully demonstrated a method to break RSA encryption using quantum computing. Led by Wang Chao from Shanghai University, the team utilized D-Wave's quantum annealing systems to unlock cryptographic methods, which have long been considered secure.

This research, published in the Chinese Journal of Computers, showcases how D-Wave's quantum technology can optimize problem-solving in ways that make attacks on encryption, like RSA, more feasible. By framing cryptographic attacks as combinatorial optimization problems, quantum computers can now efficiently solve them, posing a real threat to widely used encryption methods.

While experts have speculated that quantum computers would eventually challenge modern encryption, this study suggests that the threat might arrive sooner than anticipated. The researchers didn't stop at RSA; they also demonstrated attacks on symmetric encryption algorithms critical to the Advanced Encryption Standard (AES), including Present, Rectangle, and Gift-64 block ciphers.

Prabhjyot Kaur, a senior analyst at Everest Group, commented, "Quantum computing threatens the security of many cryptographic algorithms enterprises rely on today, such as RSA and ECC. The need for quantum-safe or post-quantum cryptographic solutions is becoming increasingly urgent."

The study's implications are profound. As quantum computing advances, organizations must reassess how they secure sensitive data. Information encrypted today could be stolen and decrypted in the future once quantum technology becomes more accessible.

The research underscores the pressing need for quantum-safe encryption methods. While some companies are already exploring these technologies, Wang Chao's findings suggest that the timeline for implementing such solutions is shrinking rapidly.

In an era where quantum attacks are no longer theoretical, the cybersecurity community faces a pivotal moment. The time to rethink encryption strategies and embrace post-quantum cryptography is now.
