Cryptography and Network Security Principles and Practices, 5th Ed.,
William Stallings, Printice Hall, 2010
The course introduces computer & network security concepts: security
goals and Services. Conventional encryption: classical techniques and
modern techniques are explained. Data Encryption Standard (DES), publickey encryption, RSA algorithm, authentication applications, IP security,
web security, and system security: viruses, worms and firewalls are
examined. Students are required to complete a practical course project;
projects are of two types: either to write a code for each explained
technique or to get a security package from the market and to make a
present of the package's features.
Aims
This course aims to introduce the main concepts of computer and network security. The course introduces
security goals and services. It also defines security threats and system's vulnerabilities. Classical and
modern encryption techniques are explained. The course includes sufficient information about network
security such as Authentication, IP security, and web security. Finally, the course looks at system-level
security such as threats of viruses and the use of firewalls.
