Chinese scientists claim to have broken encryption algorithms used in banking and #Cryptocurrencies using a quantum computer. According to researchers from Shanghai University, led by Wang Chao, they used a quantum computer developed by Canadian company D-Wave Systems. They employed a method called quantum annealing, which involves searching for the lowest energy state, to break certain algorithms.
Algorithms Under Attack
The research focused on the Present, Gift-64, and Rectangle algorithms, which form the basis of the Substitution-Permutation Network (SPN) structure. This structure supports encryption standards like AES, widely used to secure cryptocurrency wallets. While AES-256 is considered one of the most secure encryption standards, scientists warn that quantum computers may soon pose a serious threat.
How Quantum Computers Bypass Barriers
Wang's team described quantum annealing as a process similar to artificial intelligence, optimizing solutions on a global scale. Unlike traditional algorithms that explore every path, quantum tunneling allows particles to pass through barriers, enabling quantum computers to find the lowest point more efficiently. This way, quantum computers can bypass obstacles that conventional methods typically struggle with.
First Real Threat to Encryption
Wang's team emphasized that this is the first time a quantum computer has posed a real threat to encryption algorithms. Quantum computing has long been feared as a turning point that could jeopardize the cryptocurrency industry. Computers capable of breaking encryption could expose users' funds to theft on a large scale.
Limitations Prevent a Full Hack
Despite this progress, researchers pointed out that complete quantum hacks are not yet possible due to environmental factors and hardware limitations. They also stated that the quantum computer attack did not reveal specific access codes used in the tested algorithms, though the team achieved better results than previous attempts.
Future Development of Quantum Attacks
Researchers noted that further development of quantum computing could potentially expose new vulnerabilities in cryptographic systems in the future. Their findings were published on September 30 in the Chinese Journal of Computers.
Vitalik Buterin's Protection Against Quantum Computers
#etherreum co-founder #VitalikButerin has already suggested how blockchain could defend itself against quantum computers in the future. In March, he explained that a simple hard fork could mitigate the risks posed by quantum attacks. Users would need to download new wallet software, but Buterin emphasized that very few people would lose their funds in the process.
