A team from the University of Shanghai was able to decrypt RSA using D-Wave quantum computers. According to their report published in a Chinese computer science journal, Wang Zhao and his colleagues successfully attacked not only RSA, but also the more modern AES standard with combinatorial optimization.
The encryption system, which retains the name of its developers, was created in 1977 by Ron Rivest, Adi Shamir, and Leonard Adelman. Today, we use them everywhere where data security is important, from browsers to email and chat; It is also used by commerce and banks. Its improved version, AES developed by Belgians Joan Damen and Vincent Remen, was published by the US Patent Office in 2001.
The Chinese announcement is significant because quantum computers are known to be able to perform certain operations, such as analysis, much faster than classical computers, such that they can break classical encryption in hours rather than hundreds of thousands of years. Given the development of quantum computers, this has so far only been a theoretical matter, and experts have calculated that at some point in the next decade, quantum-resistant cryptographic systems will have to be introduced.
This is an era transition by definition
It is far-reaching and expensive.
Wang Zhao and his colleagues sounded a wake-up call to the crypto profession and policymakers earlier than expected. They point out in their paper that the problem requires immediate attention and action. According to analysts, this could mean a new situation where from now on you can expect cyberattacks that cannot be carried out using classical computers.
