Chinese scientists use quantum computers to crack military-grade encryption

Chinese researchers have reportedly demonstrated a significant threat to classical cryptography, particularly affecting widely used algorithms like RSA and AES. Utilizing a D-Wave quantum computer, the team led by Wang Chao from Shanghai University claims to have successfully executed a quantum attack on these cryptographic standards. Their research, detailed in a paper titled "Quantum Annealing Public Key Cryptographic Attack Algorithm Based on D-Wave Advantage," outlines two primary methods for breaching the security of substitution-permutation network (SPN) algorithms. The first method relies solely on D-Wave's quantum capabilities, while the second combines classical cryptographic techniques with quantum annealing. This advancement raises concerns about the security of military-grade encryption, as the techniques could potentially lead to the cracking of AES-256 and similar algorithms. In response to these developments, organizations like the National Institute of Standards and Technology (NIST) are actively working on post-quantum cryptographic algorithms designed to withstand future quantum attacks.

- Chinese researchers claim to have cracked military-grade encryption using quantum computers.

- The attack targets widely used algorithms like RSA and AES, posing a significant security threat.

- Two methods were developed: one using D-Wave's quantum capabilities and another combining classical and quantum techniques.

- The findings highlight the urgency for developing quantum-resistant encryption methods.

- NIST is working on post-quantum cryptographic standards to enhance security against potential quantum threats.
