Australian My Health Record - MHR System - IT - Computer Science Assignment Help

Assignment Task :

Objective: 

The objective of this assignment is to identify a set of (cyber security) algorithmic  requirements and apply the relevant symmetric and asymmetric key cryptography algorithms  for a given application (Australian My Health Record - MHR System).

A simple MHR scenario: 

MHR is an initiative by Australian government that provides a secure online summary of the health information to the individuals (e.g., health professionals and patients). It can control what goes into it and who is allowed to access the MHR system. It can choose to share patients' health information with their doctors, hospitals and other healthcare providers like pharmacists. In addition to such "primary use" of the data/information for the health services, there are plans to use aggregated and anonymised health data/information for research and other purposes - this is known as "secondary use". Overall, the MHR system controls our health information securely in one place. It is really our choice - we can keep our MHR with basic information, or we can allow more information to MHR system or permanently delete the record. An MHR user is an individual who has right to use patients' health information. For example, A Doctor can do the following actions in the MHR system: Login to the system, Access patients' health information, Write prescription, Recommend patient to the specialists. The MHR system also gives our pharmacists a clearer picture of our health information. More information about MHR can be found here: https://www.myhealthrecord.gov.au/. You can use other MHR scenarios/examples from other sources, however, please document your scenarios/examples and provide references. Please follow the word limits that are mentioned in each activity. 

Activity (1) -  Write any specific use case description of the MHR 

• Identify at least 5 use cases that can allow different users to interact with MHR system 

• Identify the possible misuse cases for those use cases (at least 5 misuse cases) 

• Select a single use case and provide the situations (i.e., a situation is seen as interactions between actors and system) for your selected use case 

• Write the description of the selected use case

Activity (2)  Write a Brief Survey on Cryptographic Algorithms: 

• Understand the basic concepts of Symmetric versus Asymmetric Key Cryptography  and briefly write your findings including a symmetric key algorithm and specific asymmetric key algorithm 

• Write your reflections on using different cipher substitution algorithms (e.g., AtBash Substitution Cipher and Caesar Cipher Substitution) for secure communication – like, two entities (or users) can communicate and interact with MHR system through creating such a secure channel

• Write your reflections on using different encryption and decryption techniques (through secret and public keys) for secure communication in the MHR system

Activity (3)- A Recent Cryptographic Algorithm: In this activity, 

• Write about your research approach to find any relevant research paper - you can use 'Google Search' or 'Google Scholar Search' to search/find your paper, and/or 'Google Dataset Search' to find the relevant dataset 

• Identify any relevant algorithm from the paper that is proposed within last five years 

• How the algorithm works and briefly describe the application area in which the algorithm is applied 

• Write your reflections on applying the proposed algorithm in the MHR system to solve any (and/or multiple) of the issues mentioned in Activity (2), like encryption/decryption, key exchange, secure communication, and so on
