Researchers at Shanghai University recently claimed to have made a significant breakthrough by cracking RSA encryption algorithms used in banking, military, and cryptocurrency sectors.
However, popular YouTuber Mental Outlaw has cast doubt on the impact of this discovery, citing several limitations that make it unlikely to affect current encryption standards.
The breakthrough, according to the research paper, involved a quantum computer that factorized the integer 2,269,753, a notable achievement that surpasses previous quantum computing records.
Quantum Computer in China Only Breaks a 22-bit Key
Despite this, Mental Outlaw pointed out that classical computers have already surpassed this level by breaking an 892-bit key, a far more substantial accomplishment.
The YouTuber noted that the quantum computer in China only managed to break a 22-bit key, a much smaller feat in comparison.
For context, early RSA encryption standards used 512-bit keys, while modern encryption methods now range between 2048 and 4096 bits.
Mental Outlaw emphasized that quantum computers, at their current stage, lack the power to break such large keys.
He also noted that quantum computers cannot be easily scaled by combining them to enhance processing power, a significant limitation in overcoming encryption barriers.
Another challenge with quantum computing is the physical environment required to maintain quantum bits.
These systems must be kept at near-absolute zero temperatures, necessitating complex cooling systems to ensure stable operation.
Furthermore, Mental Outlaw highlighted that a significant portion of quantum computing power is dedicated to error correction, meaning only a fraction of its capability is used to solve actual problems.
Despite these limitations, Mental Outlaw cautioned that advancements in quantum computing could eventually pose a threat to modern encryption, though this remains a future concern.
In response to such risks, major tech companies are already working on quantum-resistant encryption.
HSBC began experimenting with quantum-resistant banking infrastructure in 2023, while IBM and Microsoft formed a coalition to develop post-quantum encryption technologies.
More recently, Apple made iMessage quantum-resistant in early 2024, joining the race to protect digital communications against future quantum threats.
Buterin Proposes Solution of Address Threat of Quantum Computing
In response to concerns over the potential threat of quantum computing, Ethereum co-founder Vitalik Buterin has proposed a solution.
He suggested that blockchain networks could mitigate the risk by implementing a hard fork and requiring users to download new wallet software.
In a March post, Buterin emphasized that this infrastructure could be developed in advance to protect users’ funds.
In 2017, a group of researchers, including Divesh Aggarwal and Gavin Brennen, published an article warning that the elliptic curve signature scheme used by Bitcoin “could be completely broken by a quantum computer as early as 2027, by the most optimistic estimates.”
However, to be able to break cryptocurrency security, quantum computers will likely need thousands, if not millions, of qubits. Currently, the most advanced machines have around 1000.
