Cryptography in Network Security

Course Code NET-801
Lecture hours per week 2
Lab hours per week 2
Course Availability: Open

In this technical elective course, the instructor will discuss issues related to network security, cryptography, and the science of encryption. Students will study historical techniques of encryption, block ciphers and the DES. The instructor will proceed to cover the required mathematical preliminaries in abstract algebra and apply them to the AES cipher. Several topics in number theory will be introduced before focusing on public-key algorithms such as the RSA algorithm and the Diffie-Hellman Key Exchange. Additional topics will include key management, message authentication and Hash functions, and digital signatures. After a survey of the application of cryptographic algorithms and security protocols to provide security over networks, the course will conclude with some security problems and counter-measures at the system level.
