CY 5120 — Applied Cryptography
4 semester hoursGraduateLectureusually offered: fallBostonTraditional
Surveys the principles and the practices of cryptography. Overviews the core cryptographic algorithms: symmetric encryption schemes (e.g., DES and AES); public key cryptosystems (e.g., RSA and discrete logarithm); and hash functions (e.g., the SHA family). Discusses core information assurance building blocks, such as authentication, digital signatures, key management, and digital certificates. Finally, applies these concepts to important security architectures, including the IP network stack (e.g., IPsec and SSL/TLS), the cellular system, and broadcast media.
