TASK

You have been asked to develop a data transfer system from Port Macquarie to Wagga Wagga Campus. In this task, your job is to ensure that stream data is protected. In order to ensure that your system operates in a secure manner, you need to develop a prototype of your system in CryptoTool 2.  CrypTool 2 (CT2) is an open-source program offering an innovative visual programming GUI to experiment with cryptographic procedures and to animate their cascades. You can download CT2 at https://www.cryptool.org/en/cryptool2 . You can also watch Short Introduction to CrypTool 2 at https://www.youtube.com/channel/UC8_FqvQWJfZYxcSoEJ5ob-Q.

Task 1: 

In this task, you are required to

  1. Search RSA (Rivest – Shamir – Adleman) and AES (Advanced Encryption Standard) algorithms suitable for the above scenario, keep in mind that you can expand your system to more than one user,
  2. Select a cryptographic algorithm and discuss why you think your selected algorithm is appropriate for the above scenario,
  3. Design and develop a cryptographic system to encrypt live webcam data from Port Macquarie to Wagga Wagga using your chosen algorithm,
  4. Discuss the strengths and weaknesses of your system,
  5. You must document your approach with a description of the screenshots.

Task 2:  

In this task, you are required to

  1. Search HMAC,
    1. Part 1: Design and develop a message-based system to encrypt and decrypt messages using an RSA algorithm,
    2. Part 2: On the basis of Part 1 system, you should integrate the HMAC algorithm into your system,
      1. The HMAC has to check message received from Port Macquarie,
      2. If the integrity of the message approved, then decrypt the message,
      3. Else, a message, or false Boolean output.
    3. Discuss the strengths and weaknesses of your system,
    4. You must document your approach with a description of the screenshots.

Marking criteria

Criteria Max Grade
Select a cryptographic algorithm and discuss why the selected algorithm is appropriate for the above scenario. A highly suitable and efficient algorithm is selected and clear arguments are strongly supported with well-reasoned and concise discussion of logical and compelling evidence of why the algorithm was selected. 1
Design and develop a cryptographic system to encrypt live webcam data from Port Macquarie to Wagga Wagga using the chosen algorithm Designed and developed an efficient and smoothly working cryptographic system. The system shows some originality in thought.
The design  is logically organised and easy to follow		 2
Discuss the strengths and weaknesses of the system In the discussion thoroughly evaluates the strengths and weaknesses of the system showing insight and the ability to accurately, clearly and concisely articulate and apply the theory. 1
Document the approach with a description and screenshots. Documented all of the approaches with concise and highly meaningful descriptions of the screenshots. 1
Search HMAC and  Design and develop a message-based system to encrypt and decrypt messages using an RSA algorithm Designed and developed an efficient and smoothly working message-based system. The system shows some originality or innovation in thought.
The design is logically organised and easy to follow.		 6
Part 2: On the basis of Part 1 system, you should integrate the HMAC algorithm into your system,                                                  The HMAC has to check message received from Port Macquarie, If the integrity of the message approved, then decrypt the message,  Else, a message, or false Boolean output. Successful and thoughtful integration of the HMAC algorithm that does not detract from the smooth and efficient working of the system and achieves all the requirements listed. 7
Discuss the strengths and weaknesses of system In the discussion thoroughly evaluates the strengths and weaknesses of the system showing insight and the ability to accurately, clearly and concisely articulate and apply theory. 1
Document the approach with a description and screenshots. Documented all of the approach with concise and highly meaningful descriptions of the screenshots. 1
The document must be submitted within an acceptable format (cover page, full name, student ID, lecturer name, session time, etc.). 0
References using APA style Referencing is comprehensive, demonstrates academic integrity, and conforms exactly to APA style conventions.
