Course Objectives
- To learn network security issues, and understand their existing solutions using cryptography protocols.
- To learn inter-networking techniques, that is techniques and processes for connecting different networks, and the related security issues.
Course Outcomes
On successful completion of this course, the students will be able to: <br />1. Identify network and inter-networking security threats, classify the threats and develop a security model to prevent, detect and recover from the attacks. <br />2. Encrypt and decrypt messages using block ciphers, sign and verify messages using well known signature generation and verification algorithms. <br />3. Analyze existing authentication and key agreement protocols, identify the weaknesses of these protocols.
