Experimenting with Post-Quantum Cryptography
As I understand it that the picture for symmetric encryption in a quantum computer world is still relatively rosy. The key strength of something like AES is halved, but with the important caveat that the difficulty is with respect to quantum operations rather than classical operations and there's no guarantee quantum computers will be able to scale as well over time as silicon has. The situation for asymmetric encryption is where the real potential trouble lies. Please correct me if I misunderstand the situation.
