Quantum Cryptography – What Will Change?

Quantum Cryptography – What Will Change?

13th October 2021 Brigantia, Data Protection, Technology

Almost everyone has heard of quantum computing, and almost no one understands it. One of the first things that you have to learn when looking at anything to do with quantum physics is that it doesn’t seem to make much sense. The more that you know about classical physics, the less sense quantum physics makes. Don’t worry though, I am not going to try to explain it to you in this little article, any forays into the quantum realm you can do on your own at a later date.

Without delving into the magical properties of quantum physics, we can discuss what it is expected to be able to achieve, and what that means for us. When it comes to breaking codes, passwords, etc, a quantum system will make this much quicker. This is due to the sheer speed with which these systems can perform certain kinds of tasks.

What will happen to all the existing security if quantum computers make them no longer fit for purpose? These systems will become obsolete, and quantum security will be born. What will this look like? We shall have to wait and find out.

There are many ideas about things that can be developed for this purpose such as dynamic quantum cryptography and salt-hashed keys, but at the end of the day, the only thing that we should take away from this is that we should expect an arms race. Quantum computers will become more commonplace, and the clever hackers not only get their hands on them but will work out new and scary ways to get around security designed to stop them, before selling these to criminal organisations. The criminals will then target people and organisations throughout the world with these new tools, and at that point the rate of change in security will increase in an effort to counter these new threats.

At this point, one of two things will then happen:

  1. An ever-changing quantum cryptographic security will be required for everything from corporate networks to the devices in our pockets. As with this sort of problem, it will bring a raft of new opportunities for those of us who wish to sell products and services in an effort to keep organisations safe from criminals.
  2. We wind up with an unscheduled visit to the stone age when all computer-based devices cannot be used, and civilisations just cease to function.

Me, I’m holding out for option #1!  😉

Assuming that you want to stay up to date with the new security technologies as they become commercially available, then simply stick close to Brigantia. As the technologies evolve, Brigantia evolves along with it.
