Quantum computing has the ability to change the world, both for better and worse, and while it may be far off in the future, security teams need to start preparing for the new reality it will usher in.
For better: quantum computers promise to power advances in different fields that would have been unthinkable even a couple of years ago. From the creation of new pharmaceuticals to the simulation of election results, quantum computing offers real and tangible benefits. Already, we’re seeing companies like Google declare “quantum supremacy” in reducing computations from tens of thousands of years to seconds.
Yet as we enter what IBM has termed the Quantum Ready stage of our existence, we can’t afford to ignore the worse, particularly when it comes to quantum computing cybersecurity. Think of a computer that can brute force decrypt a complex high security algorithm, such as RSA, in mere seconds. Then, think of what a hacker could do with such a powerful tool. They could potentially use the power of quantum computing to easily hack into any enterprise network or decrypt sensitive messages with relative ease. It would be like giving them the greatest gift they could ask for.
Some may see this as alarmist. After all, sure, Google may have run some tests and gotten some great results. But, it’s not like quantum computing is ubiquitous. It’s still in the future. Nothing to worry about.
But that’s just not correct.
