What to do about Quantum Computing?
There's a good (if geeky) read from the UK National Cyber Security Centre on how to prepare your organization for Quantum Computing. From the article:
Quantum computers use properties of quantum mechanics to compute in a fundamentally different way from today's digital, 'classical', computers. They are, theoretically, capable of performing certain computations that would not be feasible for classical computers. Although advances in quantum computing technology continue to be made, quantum computers today are still limited, and suffer from relatively high error rates in each operation they perform.
In the future, it is possible that error rates can be lowered such that a large, general-purpose quantum computer could exist. It is, however, impossible to predict when this may happen as many engineering and physical challenges must be overcome first. If such a computer could exist in the future, most traditional public key cryptography (PKC) algorithms in use today will be vulnerable to attacks from it.
Breaking Public Key Crypto is A Very Bad Thing Indeed, and would basically break the Internet. If you're in the security field, you really should read this.
