3 Learning Outcomes This assessment assesses the following Unit Learning Outcomes (ULO) and related Graduate Learning Outcomes (GLO): Unit Learning Outcome (ULO) ULO3-Apply principles of public key cryptography to achieve secure communication networks by using digital certificates and digital signatures in compliance with industry standards. ULO4-Justify the use of cryptographic schemes on networked infrastructures to prevent the misuse of technology. Graduate Learning Outcome (GLO) GLO1: Discipline knowledge and capabilities GLO4: Critical thinking GLOS: Problem solving GLO1: Discipline knowledge and capabilities GLO4: Critical thinking GLOS: Problem solving Purpose This assessment allows you to demonstrate your ability to send confidential messages. Instructions This is an individual assessment task. Create a public and private key pair to encrypt and decrypt a message. Students should submit the following files: The message: This should be a text file, which contains your "encrypted" message. The message should contain your student ID and name (message.txt). You should use the openssl commands. The document: This should be a .pdf file of no more than four pages, split in three sections with cosponsoring openssl command's (and provide screenshots of each step): o Section 1: List the openssl commands you used to encrypt the message. o Section 2: "List" the openssl commands (including options and parameters) that you used to decrypt the message. Note that, those commands will be executed within the folder where the encrypted message is located. o Section 3: "Describe" the communication protocol you have used to communicate in graphical notation, such as Alice and Bob notation. Use the description of the protocol to explain how authenticity of the sender and integrity of the message are achieved. If further openssl command to verify authenticity and/or integrity are needed, please, add them too. • Keys: Cryptographic keys necessary for encryption or decryption (that is generated public and private keys). Do not zip your files./nAssessment Information Important technical information: Encryption and decryption will be done with the command line tool using openssl. Each instruction should be in the form of an openssl instruction to be executed within the folder where the submitted files are downloaded. The current stable version of openssl is 3. See the rubric below for more details on what we expect from you. Submission details The files must be submitted via CloudDeakin no later than Sunday 20 August 2023, 11.55pm (AEST). Extension requests Requests for extensions should be made to Unit/Campus Chairs well in advance of the assessment due date.

Academic integrity, plagiarism and collusion Plagiarism and collusion constitute extremely serious breaches of academic integrity. They are forms of cheating, and severe penalties are associated with them, including cancellation of marks for a specific assignment, for a specific unit or even exclusion from the course. If you are ever in doubt about how to properly use and cite a source of information refer to the referencing site above. Plagiarism occurs when a student passes off as the student's own work, or copies without acknowledgement as to its authorship, the work of any other person or resubmits their own work from a previous assessment task. Collusion occurs when a student obtains the agreement of another person for a fraudulent purpose, with the intent of obtaining an advantage in submitting an assignment or other work. Work submitted may be reproduced and/or communicated by the university for the purpose of assuring academic integrity of submissions: https://www.deakin.edu.au/students/study- support/referencing/academic-integrity
