CSC 432 - 3 Semester Hours
Introduction to the theory and practice of cryptography and cryptanalysis. Theoretical underpinnings of modern cryptosystems will be examined and unproven assumptions exposed. Both symmetric- and public-key cryptosystems will be covered. Applications of cryptography to identification, authentication and non-repudiation protocols. Zero-knowledge protocols and oblivious transfer. Cryptanalytical attacks.Economic, political and ethical issues raised by strong cryptography will be discussed.
CSC 241 and MAT 215
Strong cryptography is now available to any group or individual that wants it. Banks, online shoppers, drug dealers and terrorists alike rely upon this technology to secure their communications and data from prying. Yet is it possible that the most popular public-key cryptosystem is without foundation.
Students will learn the strengths and (potential) weaknesses of various encryption schemes. As they grow more comfortable with the underlying theory, they should become fairly sophisticated users of cryptosystems, able to negotiate trade-offs (e.g., between key length and efficiency) to suit particular applications.
Moreover, computer science students should know the pitfalls of living in a networked world where governments and marketers have greatly increased their ability to collect and integrate personal information from widely disparate sources.
