This course is designed, to introduce the fundamental components of cryptography, namely symmetric and public key algorithms, and examine the key management issues relating to the use of these techniques. This topic is approached in a non-mathematical way.

Target audience

~      Information Security Managers
~      Security Team Leaders
~      Security Team Members
~      IT Technical Staff
~      System Designers and Implimenters
