Chinese Researchers Use D-Wave Quantum Computer to Crack Key Encryption Algorithms, Sparking Security Concerns
China’s scientists have reportedly used Western quantum computing technology, specifically from D-Wave, to crack encryption algorithms that were once deemed unbreakable. This breakthrough marks a significant step forward for the emerging field of quantum cryptography and raises concerns about the security of critical digital infrastructures.
According to a report by the South China Morning Post, a team of researchers led by Wang Chao from Shanghai University has successfully broken some of the most widely used encryption algorithms. In a peer-reviewed paper, the team describes this advancement as a “real and substantial threat” to encryption methods currently used in sectors such as banking and the military.
The researchers utilized a quantum computer from Canada's D-Wave to crack foundational encryption algorithms, including Present, Gift-64, and Rectangle. These algorithms play a crucial role in the security framework of digital systems globally. The team employed a technique known as quantum annealing; a process central to D-Wave’s computing technology. This process uses quantum fluctuations to identify the global minimum in possible solutions.
Quantum Breakthrough Could Threaten AES-256 Encryption, Raising Alarms Over Future Digital Security
By combining quantum annealing with conventional mathematical techniques, Wang Chao’s team developed a novel computational architecture capable of breaking widely used encryption methods. Most notably, the researchers believe this method could eventually be used to crack AES-256, an encryption standard widely regarded as “military-grade” due to its robustness.
While the method has yet to reveal encrypted passcodes, the researchers are closer than ever to achieving this outcome. However, several limitations still need to be addressed, including environmental factors, hardware being developed, and creating a single attack strategy that can breach multiple encryption algorithms.
According to Wccftech, this development raises serious questions about the future of digital security, particularly as quantum computing advances and its potential for innovation and disruption becomes more apparent.
