New York University 3 credits Computer Science
This course first introduces the fundamental mathematical cryptographic algorithms, focusing on those that are used in current systems. To the extent feasible, the mathematical properties of the cryptographic algorithms are justified, using elementary mathematical tools. Second, actual security mechanisms and protocols, mainly those employed for network traffic that rely on the previously introduced cryptographic algorithms, are presented. The topics covered will include introduction to basic number- theoretical properties, public/private and symmetric key systems, secure hash functions, digital signature standards, digital certificates, IP security, email security, web security, and stand-alone computer privacy and security tools.
