Assignment Task:

Module Learning Outcomes
The following Los is achieved by the student by completing the assignment successfully
1. Demonstrate an understanding of cryptography and digital signatures
2. Demonstrate an understanding of authentication requirements and applications
3. Design and Configure Microsoft Forefront Threat Management Gateway and implement network polices

Assignment Objective

Assignment Tasks
Task 1
Secure information and communication techniques derived from mathematical concepts and a set of rule-based calculations called algorithms, to transform messages in ways that are hard to decipher. These deterministic algorithms are used for cryptographic key generation, digital signing, verification to protect data privacy, web browsing on the internet, and confidential communications such as credit card transactions. One of the cryptography types is asymmetric cryptography that is used to provide data confidentiality and non-repudiation. One of the most common algorithm in this type is RSA. Assume the RSA algorithm parameters are ( p = 29, q = 23 and e =17)
a. Explain the process of securing the communication between two parties using asymmetric cryptography.
b. Using the given RSA parameters, Generate your key pairs for asymmetric cryptography.
c. Suppose Ali wants to send you the PIN cod = 124 confidentially. Discuss in details, how to exchange this PIN code by implementing RSA algorithm.
d. Explain how you will use asymmetric cryptography in a digital signature.
e. Critically evaluate the security attacks on asymmetric cryptography.

Task 2
Authentication is element of a typical security model. It is the process of confirming the identification of a user (or in some cases, a machine) that is trying to log on or access resources. There is a number of different authentication mechanisms, but all serve this same purpose.
a. Critically analyze any five user authentication mechanisms. (20 marks)
b. Critically evaluate the security threats for each authentication mechanism.
