The goal of this course is to acquaint the students with security issues in multi-user information systems and computer networks and to provide them with training in the fundamental techniques, particularly cryptography, for security and their applications in practical areas such as electronic commerce, network intrusion protection, and security management.

Operating Systems and Computer Networks

• Cryptography and Network Security: Principles and Practices, 5th Edition, W. Stallings, Prentice Hall, 2010. (Note: be sure to check out the errata list on the Web site of the book!)

• Supplementary readings.

We will study the design and underlying principles of automated tools for protecting information, including software and data, stored on computers or communicated over networks. The main focus will be on the fundamentals and applications of cryptographic technology. We will follow mainly the textbook of W. Stallings and enhance the contents with class notes and supplementary readings.
