Last August, the Institute of National Standards and Technology (NIST) released the first three « After the Quantum Encryption Standards« It’s designed to endure a guard from a quantum. For years Cryptography experts are concerned about the fact that quantum calculations can write a doomsday for traditional Encryption methods. Now the horizon represents a first meaningful step for new NIST standards, quantum quantum protection with solid technology.
But the quantum calculates the threat to encryption, which has been done? It is true that quantum computers can break the traditional encryption faster and more easily, we still travel a long way in the « no more mystery » encryption box in 1992 Sneakers. Energy requirements and calculation strength limits still limiting factors, with access to quantum computers, taking into account the use of technology to better use – as science, pharmaceutical and healthcare.
Remember the theory of electron microscope?
I have worked for a long time in the digital trial and a unique perspective for the difficulties of quantum calculation. In 1996, Peter Gutman published a white paper called « Magnetic and Strong State Memory, which can delete data from a stable disk using an electron microscope. Was it possible? Maybe -, but as a result, the process would be incredibly hardworking, resource intense and invalid. The more importantly, it was not a large number because it was not the hope of restoring the deleted data from an electron microscope before storing such intensive drivers.
In fact, there is almost no evidence that such an electron microscope is never used successfully for this purpose and The modern test confirms The method is neither practical nor reliable. However, fear was real, and this was a method of deleting the popular « 7 passesion » method to eliminate any judgment that the electric microscope can identify. Should we take additional measures with sensitive or classified information? Of course. However, the threat was closer together. When it comes to quantum calculations, we can start a similar way.
Quantum Computing Practical Reality
First, it is important to understand how quantum calculations work. Although the films look like describing hackers, this is not a magic wand that will immediately finish cryptography as we know. It still needs to be fed with separate messages and encrypt – which means that the messages of the attackers should be a very good idea because the valuable information is. It may seem easy, but more 300 billion e-mail Sending with texts with trillions every day. There are ways to narrow the search field but still required aggressor To throw a horrible amount of computing power in the problem.
This leads me to a real matter: the computing power is not infinite. Quantum is on the advanced edge of computing technology, which means the average script or means hacker collective will not be able to get their hands on top. Quantum will be the only player who can get computers (and the energy needed to use), Google, Microsoft and AI companies will be nation-state actors and large corporations. To put it just, quantum calculation will first have a large number of themes and the nations will have so much computing power in them. The question is then that’s what: breaking encryption protocols really plan to spend it?
Real use cases for Quantum
The answer is strong … maybe. To me, the true advantages of quantum have research, economic competition and global impact. This will not use quantum computers, if an enemy nation-state is handling, quantum computers will not use cracking encryption – but technology will not be the main way. See this way: If you have a foreign power with access to the most advanced computer models on earth, why would you use them? Would you rather a wild gas chase with millions of encrypted communication or would you like to create this critical time, energy and treatment cancer, eliminate or develop new materials? To me, this is no brain. After short-term gain, there may be an individual aggressive, but the nations will think for a longer period.
Are likely to drive quantum computing Significant improvements In preparation of new materials and catalysts that cause more powerful, lighter composites to produce and more jet catalysts for chemical processes. This has the potential to revolutionize more than one area that provides a long-term profit for the deployment of technology. Quantum calculation is also promised in the pharmaceutical industry that helps the development of leading researchers More effective drugs and other treatments in a part of time. Technology is used to even increase Space travel opportunities By activating faster trajectory calculations, navigation optimizes more accurate and fuel use.
This comes to expense-benefit analysis. Only nations and major corporations can get quantum calculations soon and will they spend the use of really limited calculation power cracking encryption algorithms to increase economic output and dominant financial markets instead? This is not to say that every use for quantum calculation is good – in the wrong hands, no doubt can be used dangerously. But the so-called « quantum apocalypse » we believe in some attention, context issues.
Quantum breaks the encryption in the list of use for calculations? Yes. But it’s not high on the list. Therefore, before we change each cryptographic algorithm to spend and use billions of dollars, you may think of a deep breath and how to use quantum calculation.
