A single-core computer was used to crack the encryption developed against quantum computers

There is still a lot of work to be done by cybersecurity scientists to develop appropriate defenses.

Humanity is on the brink of a quantum computer revolution, which will double the computing power of existing computers, but new technology can bring more than just positive changes to the world.

One of the serious problems that must be solved is that the encryption methods used today are completely undefensible against the capabilities of quantum computers, so a new protection solution must be developed before it becomes widespread. That’s the goal of a program announced by the US Department of Commerce’s National Institute of Standards and Technology (NIST), one of whose promising candidates is now bleeding hard against conventional technologies.

The Seki (supersymmetric key encapsulation) The algorithm was already in the third round of competition supervised by NIST, that is, it was on the verge of becoming an official standard one day, but the scientists of the Catholic University of Leuven, much to their surprise, showed astonishingly that it was unsuitable for encryption against quantum computers.

Belgian scientists have cracked the SIKE protection with a simple single-core computer, by completely bypassing the encrypted keys: the high-level mathematical algorithm they developed revealed the basics of the SIKE cipher scheme, so that it could predict in advance the solution keys produced by the technology. Study (in English) about it It can be read by clicking here. The scientists received a reward of $50,000 (approximately 20 million HUF) for their work, under the Microsoft-backed Vulnerability Research Program.

The complexity of anti-quantum protection is shown by the fact that SIKE is indeed the second most promising algorithm that has been proven unsuitable for its task in recent months: in February, A solution called rainbow has been hacked (theoretically).. It wouldn’t hurt to rush to solve the challenge, however, because, according to experts, the first cyberattacks using quantum computers will certainly happen this decade, which is still something to protect. the scientist almost encrypted. 64 zettabytes data.
