This talk is an introduction to the field of quantum hardening. The introduction of practical quantum computers will render existing cryptographic protocols unsafe. At what point we need to start worrying and what can be done to remedy this problem is the focus of this talk. The talk begins with an introduction to the design of modern cryptographic protocols in general.
If you would like to skip the crypto introduction and cut to the quantum hardening part, jump to minute 29:00.
