Once a cutting-edge sci-fi theory, quantum encryption – along with the computing power that drives it – may be close to wide-scale deployment. When it comes online, all previous cryptographic standards used to protect our data could go up in smoke.
With every tool that could change the world comes questions of scale and mass deployment. Is it ready to be rolled out for wide use? How should chief information security officers (CISOs) prepare for this major change?
Quantum Encryption 101
In a nutshell, quantum computing allows us to do more in less time. Computing no longer is binary between zeros and ones; everything in between is fair game. Instead of bits, we have quantum bits, or qubits, allowing complex, multidimensional computations.
For the purposes of encryption, quantum computing would allow an attacker to cut down the time needed to crack a code. Government agencies work on quantum computing for this purpose. Therefore, as we move out of the theoretical space, the issue CISOs should be concerned with is less “if” and more “what do I need to do and by when?”
Preparing to Quantum-Proof Your Business
How can CISOs, risk managers and all those interested protect their data in the post-quantum world?
Quantum-proofing your protection should be on your mid- to long-term radar. Your near-term longevity as a CISO will likely depend on making your environment quantum-safe. Expect big changes within the next three to five years (though some a ..
