Abstract:
Quantum channels have unique properties and can enable new security
algorithms.
One of these algorithms, BB84, is to be implemented at NIST.
The talk will be
- a very quick tutorial on BB84 which relies on quantum
communications to create ideally-identical shared bit sequences in
communicating computers and then uses classical means to extract
out of these sequences create shared secrets to be used as
one-time pads.
- a reasonably detailed exposition of the techniques used to extract
out of the bits in (1) shared secrets that are shared and secret
with arbitrarily high probability.
- Possible alternatives to (2)
- (if time permits) Practical questions on how to implement BB84 and
use its output within a communication stack.
