Crypto Graphic Techniques and Data Security

With the widespread use of computers and internet as well as the rapid spread of electronic commerce, computer security has become very important. This course introduces the main cryptographic methods for communication and computer system security.

The topics include:

• Symmetric-Key ciphers
• Mathematics of Cryptography
• Data Encryption Standard
• Advanced Encryption Standard

Upon the successful completion of this course, students should be able to:

• have internalized the fundamental notions of threat, vulnerability, attack and countermeasure.
• be able to identify the security goals of an information system, point out contradictory goals and suggest compromises.
• have a theoretical understanding of the principles underlying cryptography and cryptanalysis and have a technical understanding of the main cryptographic concepts and technologies available today, including symmetric and asymmetric encryption, hashing, and digital signatures.
• understand the purpose of security protocols and be witness to the difficulties of their verification.
