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.
