One of the biggest fears is that quantum cryptography could break classical encryption that underpins financial stability and the global economy. Cryptography is something that we all take for granted in everything from messaging apps to online banking. But if quantum lives up to its future promises, we could have the genuine problem of it breaking cryptography within the next decade. For example, Intelligence services equipped with quantum computers, in theory, they would be able to break 2048-bit RSA encryption in under 8 hours. In comparison, the same task would take the world’s fastest supercomputers around 300 trillion years to overcome with traditional brute-force methods. Many are warning of a modern Y2Q the Q-Day moment waiting on the near horizon that businesses need to prepare for now. With everything from toasters to smart cities connected to the internet, the logistics of transitioning the whole world to new post-quantum algorithms that are resistant to quantum computing cyberattacks is no small feat. As end-to-end systems become more deeply interconnected, businesses must secure and safeguard their entire critical cyberinfrastructure. Unfortunately, traditional threat detection software will be incapable of going toe to toe or even identifying malicious attacks by quantum computers.
