The UMBC Cyber Defense Lab presents

An Introduction to Quantum Cryptography:
Or, How Alice Outwits Eve

Sam Lomonaco, CSEE, UMBC
12:00–1:00pm, Friday, 17 November 2017, ITE 231, UMBC

Alice and Bob wish to communicate without the archvillainess Eve eavesdropping on their conversation. Alice decides to take two college courses, one in cryptography, the other in quantum mechanics. During the courses, she discovers she can use what she has 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 Vernam cipher, the BB84 and B92 cryptographic protocols. The talk ends with a discussion of some of Eve’s possible eavesdropping strategies, i.e., opaque eavesdropping, translucent eavesdropping, and translucent eavesdropping with entanglement.

Samuel J. Lomonaco Jr. received his PhD in mathematics from Princeton University. He has been a full professor of computer science and electrical engineering at the University of Maryland, Baltimore County (UMBC) since 1985, serving as founding chair of the CS Department from 1985 to 1991. Representative Awards, Accomplishments, and Honors include: (1) He was a visiting key research scientist at the Mathematical Sciences Research Institute (MSRI) at the University of California at Berkley in 2004. (2) He was a senior LaGrange fellow at the Institute for Scientific Exchange in Torino, Italy in 2005. (3) For contributions made to the development of the programming language Ada, he received an award from the United States Under Secretary of Defense for Research and Engineering, Dr. Richard DeLauer. (4) He was the first to introduce quantum information science to the American Mathematical Society (AMS) by organizing and giving a two-day AMS short course on quantum computation at the Annual Meeting of the AMS in Washington, DC, in January 2000. (5) He published four books on quantum computation and information science. (6) He accepted an invitation to be a guest editor of the Journal of Quantum Information Processing for a special issue on topological quantum computation.
