In my opinion, this is an interesting problem: We are very used to today’s asymmetric crypto algorithms, which all base on the problem that it is unbelievably hard to factor a very large number into primes. A hard mathematical problem and security of the Internet is based on it.
Now, with quantum computing, this mathematical problem might be solved in fractions of a second and boom, encryption will fail, it is almost clear text. This is not a doom’s day scenario, it can actually happen faster than we think or it might be that a government has this technology already available. It just needs one computer â€“ not the availability on the consumer market.
It rarely see companies, when they look at their crypto policy, already addressing this issue. If you did not, this is actually an interesting article by Microsoft research: Securing Today’s Data Against Tomorrow’s Quantum Computers (and it is interesting if you did already as well).
