Study Indicates Quantum Attack on Cryptocurrency Could Reek a 99.2% Collapse in Value?

Everyone was stunned when the new mayor of New York City Eric Adams announced he was planning to receive his first three paychecks in Bitcoin, the cryptocurrency that’s been dominating the financial headlines for the past year. The mayor of Miami, Francis Suarez, had already announced he would accept his first paycheck 100% in Bitcoin. The mayoral announcements are still more signs that cryptocurrencies are no longer esoteric investments for the super-rich (or super-crooks) but have entered the financial mainstream. Back in May Deutsche Bank pronounced Bitcoin the third biggest world currency in terms of circulation. Only the euro and the U.S. dollar are bigger.

The Quantum Revolution – Why You Should Pay Attention Now

If you haven’t heard about quantum computers yet, you may have been spending too much time in the server room, but you will be forgiven if you have missed the numerous recent news articles demonstrating the pace of advancements in quantum computing and just how close we are to them becoming reality. And the answer is ‘sooner than you think’.  The technology giants we are familiar with today such as Amazon, Google, Microsoft, and IBM are investing hugely in this revolutionary technology, alongside an increasing multitude of innovative well-funded start-ups. But why bother?

The Basics on Preparing for a Post-Quantum Computing World

Using quantum computing, attackers can likely break even the most advanced encryption methods. The greatest concerns are Shor’s Algorithm and Grover’s Algorithm, which are two of the most touted capabilities of quantum computing. Once these are easy for attackers to obtain, they will be able to use these algorithms to break existing symmetric, and asymmetric, defenses.

Take it or Leave it: U.S. National Security Agency Gave Us the Questions They Asked Themselves, and the Answers They Gave Themselves

Quantum computers can, in principle, perform certain mathematical algorithms exponentially faster than a classical computer. In place of ordinary bits used by today’s computers, quantum computers use “qubits” that behave and interact according to the laws of quantum mechanics. This quantum physics-based behavior would enable a sufficiently large-scale quantum computer to perform specific mathematical calculations that would be infeasible for any conventional computer.

The Battle for Post-Quantum Security Will be Won by Agility

By Thomas Poeppelmann and Martin Schlaeffer
Due to their special features, quantum computers have the disruptive potential to replace existing conventional computers in many applications. They could, for example, calculate simulations of complex molecules for the chemical and pharmaceutical industry, perform complicated optimizations for the automotive and aviation industry, or create new findings from the analysis of complex financial data. At the same time, quantum computers also raise a lot of security concerns, and while today they don’t have real world applications, their capabilities are expected to grow significantly over the next 10 years. According to Michele Mosca, there is only a 14% chance that RSA2048 will be broken by 2026, but that grows to 50% by 2031. The security community has taken notice and is already preparing for quantum attacks.
