Much of today’s internet traffic is encrypted, well over 50% by some estimates. As the encryption of data in motion approaches 100%, so to does the approach of quantum computers. The threat, and mitigation, is found in this un-refined disruptive technology. How much does your CSO know of quantum computing? This piece answers some basic questions: How do quantum computers work? How do they break cryptography? How does a random number generator fit into the quantum cryptography question? Well worth the read to get a primer or to get a reminder of what lurks in the coming era of quantum computers. Because quantum is coming.
