Objective:

The objective of this assignment is to explore Information Security and Assurance (IS&A)concept and application using Cryptography. Through this assignment, you are required to do secondary research in addressing some of the challenges you will encounter. The final submission must be in a report format (as per the sample posted on blackboard).

Deliverables: A single report document answering all listed questions or with results of activities. The final document must meet the submission requirements at the end of this document.

Part A: Cryptography (100 Marks)
