About ten years ago I became interested in Latin squares. A friend who was at the Clay Institute at the time mentioned that applications for Latin squares were exploding, and that they were being utilized in quantum cryptography.
I've found a paper discussing use of Latin squares in cryptography in general (p.8 in linked doc), but can't find direct info on their uses in quantum cryptography.
This paper also makes reference to a paper entitled: "A message authentication code based on Latin Squares" from the Australasian Conference on Information Security and Privacy.
However I'm having trouble finding direct references to Latin squares in quantum cryptography.
Basically, I'm trying to get a high-level understanding of this association, if it is indeed accurate. Any info or insight would be appreciated.
