Data Security II

Course Code C0673 Th 4 Pr 4 CrHrs 3

This Course presents the principles of data security and the science behind every form of security starting with the conventional encryption systems to the modern encryption systems. So, the students will acquire the knowledge about most of common cryptographic techniques along with most common types of attacks that can be utilized to ruin the security of these techniques.  

       At the end of this course the students should have the ability to: 

  1. Design secure system based on cryptographic algorithms.
  2. Differentiate between types of encryption algorithms and be able to choose the best one based on its level of security. 

c. Analyze most common types of attacks and find ways to defend the system from these attacks.

Ill ustrate the use of Public and Private Key algorithms in building secure and modern system.
