In this course you will learn about cryptography and system security concepts.

This course provides an in-depth exploration of system security goals and concepts, focusing on confidentiality, integrity, availability, and related principles such as authentication and non-repudiation. It delves into classical and modern encryption techniques, including symmetric and asymmetric algorithms, and the application of these methods to solve problems related to data confidentiality and authentication. The course covers hashing algorithms for data integrity and the analysis of digital signature schemes to ensure secure communication. Students will also learn to design secure applications, analyze network vulnerabilities, and evaluate various attacks. The course includes an evaluation of firewalls and key security protocols such as SSL/TLS, IPSec, and PGP, preparing students to effectively implement and assess security measures in real-world scenarios.
