Title:
Abstract: Alice and Bob wish to communicate without the arch-villain Eve eavesdropping on their conversation. Alice, who has just taken two college courses (one in cryptography, the other in quantum mechanics), uses what she has just learned to devise a cryptographic communication system that automatically detects whether or not Eve is up to her villainous eavesdropping. Some of the topics discussed are Heisenberg's Uncertainty Principle, the Vernan cipher, the BB84 and B92 cryptographic protocols. The talk ends with a discussion of some of Eve's possible eavesdropping strategies, opaque eavesdropping, translucent eavesdropping, and translucent eavesdropping with entanglement. This talk is based on a paper found at the website Lecturenotes which will soon appear in Cryptologia.
