Course Objectives

To teach the security functions. To teach that which security functions are realized by which cryptographic tools. Teaching the relationship between the historical evolution of the symmetrical/asymmetrical cryptosystems and the developments of the technological and social life. Teaching that how the measure of the security level for cryptographic solutions and how the implement the international standards. To teach the currently relevant security solutions of information and communication technologies.
