Overview

Course Prescription

An introduction to data communications: the OSI reference model, particularly how the lower layers combine to implement the application layer. An introduction to secure communication and computer systems.

Course Overview

This course consists of two parts; a networking and a security part. The networking part introduces the basics of networking with the TCP/IP protocol stack in networks with switches and routers and familiarises students with the fundamental concepts that underpin it: layered communication, encapsulation and packet forwarding based on address. It also introduces students to network partitioning and topology. The security part introduces various aspects of encryption to secure communication between parties. It familiarises students with the fundamentals of classic cryptography, and how confidentiality and integrity are realised in shared-key and public-key cryptosystems. 

This course is of interest to those who would like to explore the fields of computer networks and digital security.

Key Topics

  • Components of physical networks, switches, routers, layered communication, protocols, the OSI stack, the TCP/IP stack, MAC addresses, IPv4 addressing, IPv4 netmasks, IP subnetting, CIDR notation, ARP, DHCP, IP forwarding, transport protocols, UDP, TCP, packet loss, sequence numbers and acknowledgements.
  • Classic cryptography. Shared-key cryptosystems and message integrity. Secure exchange of secret keys. Public-key cryptosystems and message integrity. Introduction to HTTP and HTTP security. HTTP latencies and performance. Transport layer security - HTTPS. Additional topics such as Steganography.

Learning Continuity

Academic Integrity

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed for potential plagiarism or other forms of academic misconduct, using computerised detection mechanisms.

Similarly, research students must meet the University’s expectations of good research practice. This requires:

  • Honesty - in all aspects of research work
  • Accountability - in the conduct of research
  • Professional courtesy and fairness – in working with others
  • Good stewardship – on behalf of others
  • Transparency – of research process and presentation of results
  • Clarity - communication to be understandable, explainable and accessible

For more information on the University’s expectations of academic integrity, please see the Academic Conduct section of the University policy hub.

Disclaimer

Elements of this outline may be subject to change. The latest information about taught courses is made available to enrolled students in Canvas.

Students may be asked to submit assessments digitally. The University reserves the right to conduct scheduled tests and examinations online or through the use of computers or other electronic devices. Where tests or examinations are conducted online remote invigilation arrangements may be used. In exceptional circumstances changes to elements of this course may be necessary at short notice. Students enrolled in this course will be informed of any such changes and the reasons for them, as soon as possible, through Canvas.


Additional Information on Academic integrity

Sharing assignment solutions and source code does not help learning. Consequently, our academic integrity policy does not permit sharing of solutions or source code leading to solutions, nor does it allow sourcing solutions or source code from any third party. Violation of this will result in your assignment submission attracting no marks, and you may face further disciplinary action. Therefore, please do not share assignments, assignment solutions and/or source code leading to assignment solutions, or use material from others in your assignments. You must not publish assignments or solutions in any form online at any time. There are also copyright and IP issues. Please come talk to us if you have any doubts about what is legitimate and what is not. You can refer to online tutorials and resources. However, please learn from them and implement the solutions yourself based on what you learnt from those sources. Do not blindly copy from online sources. Don't leave your computers, devices, and belongings unattended - you must secure these at all times to prevent anyone from having access to your assignments or solutions. If others are found to have used your assignments or solutions, you will also face disciplinary action.

Student Feedback, Support and Charter

Student Feedback

Feedback on taught courses is gathered from students at the end of each semester through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback and respond with summaries and actions. Your feedback helps teachers to improve the course and its delivery for future students. In addition, class Representatives in each class can take feedback to the department and faculty staff-student consultative committees.

Additional Information on Student Feedback

Throughout the course, students are encouraged to provide feedback.

Class representatives

Class representatives are students tasked with representing student issues to departments, faculties, and the wider university. If you have a complaint about this course, please contact your class rep who will know how to raise it in the right channels. See your departmental noticeboard for contact details for your class reps.

Tuākana

Tuākana is a multi-faceted programme for Māori and Pacific students providing topic specific tutorials, one-on-one sessions, test and exam preparation and more. Explore your options at Tuakana Learning Communities.

Additional Information on Tuākana

The course is supported by the Computer Science Tuākana programme.

Inclusive Learning

All students are asked to discuss any impairment related requirements privately, face to face and/or in written form with the course coordinator, lecturer or tutor.

Student Disability Services also provides support for students with a wide range of impairments, both visible and invisible, to succeed and excel at the University. For more information and contact details, please visit the Student Disability Services’ website.

Wellbeing

We all go through tough times during the semester, or see our friends struggling. There is lots of help out there - please see the Support Services page for information on support services in the University and the wider community.

Special Circumstances

If your ability to complete assessed work is affected by illness or other personal circumstances outside of your control, contact a member of teaching staff as soon as possible before the assessment is due. If your personal circumstances significantly affect your performance, or preparation, for an exam or eligible written test, refer to the University’s aegrotat or compassionate consideration page. This should be done as soon as possible and no later than seven days after the affected test or exam date.

Student Charter and Responsibilities

The Student Charter assumes and acknowledges that students are active participants in the learning process and that they have responsibilities to the institution and the international community of scholars. The University expects that students will act at all times in a way that demonstrates respect for the rights of other students and staff so that the learning environment is both safe and productive. For further information visit Student Charter.

Student Academic Complaints and Disputes

Students with concerns about teaching including how a course is delivered, the resources provided, or supervision arrangements, have the right to express their concerns and seek resolution. The university encourages informal resolution where possible, as this is quicker and less stressful. For information on the informal and formal complaints processes, please refer to the Student Academic Complaints Statute in the Student Policies and Guidelines section of the Policy Hub.
