At the Can-Tech (formerly known as IT.Can) conference this week Mike Brown of Isara Corporation spoke about quantum computing and security. Within a few short years quantum computing will become commercially viable. Quantum computing works differently than the binary computing we have today. It will be able to do things that even today’s super computers can’t.
For the most part that is a good thing. The downside is that quantum computers will be able to break many current forms of encryption. So it will be necessary to update current encryption models with something different.
That may not be a simple or quick exercise, given the layers and complexity of encryption. His message was that we need to start planning for this now, and it may take an effort greater and more challenging than the one that fixed the Y2K problem.
For the record, Isara sells security solutions that are designed to be quantum computer safe. For some validation that this really is a thing, take a look at this Wikipedia article on Post-quantum cryptography.
