The quantum security quandary

Quantum computing is an inevitable technology, with the private sector and nation-states racing to be the first to unlock its potential. While it can be used for all kinds of good, quantum computing could also be used to unravel critical systems.One of the most common ways to protect data is to encrypt it using an RSA algorithm. In simple terms, it relies on the fact that while you can easily multiply one prime number by another, it’s very hard to work out prime factors from any given number. Quantum computing could make this much easier, allowing criminals to decrypt sensitive data.The UK is among a number of nations investing in quantum computing, with the government having recently announced £900 million for exascale quantum computer. Stakes are high as we enter into what some have dubbed a ‘quantum arms race’, with the first to successfully crack encryption holding all the cards when it comes to its myriad use cases.In this episode, Rory and Jane speak to Tim Callan, chief experience officer at cyber security firm Sectigo, about the current state of quantum computing research and how the industry can prepare for this seismic shift.For more information, read the show notes here.
