Part A: Comparative Analysis [8 marks]

1. Please elaborate your understanding about how RFID and NFC work. What are the current security considerations and challenges? [ 4 marks]

2. Set up a wireless network by using Packet Tracer simulation software. Select generic laptops and access points from the list of available devices and configure the wireless connections as shown in the figure below.

Make sure that initially there is no security on either the access points or the wireless clients. Implement in each Basic Service Set (BSS) in turn, the WPA2-PSK model of security with AES encryption, and note that as each link invokes this security feature, the connection initially is lost until both sides of the link authenticate to each other. The security model must be identical for every respective link between the client and access point in each BSS. Screenshot and report your test on the following sub-questions:

a) Does every laptop ping every other laptop through the authenticated connections? Explain the communication process in brief. b) What happens when the channel is changed on any of the access points? c) What happens if there is a passphrase mismatch between the clients and the access points?

Part B: Innovative Project (7 marks)

For this assessment item you need to work in a team of two, find your partner and run group meetings, then report your target project scope to your lecturer for approval. Your team must submit a recorded presentation.

In the current age of the Internet of Things (IoT), massive smart devices are connected wirelessly. Examples include the smart light, smart sensors, smart city, etc. With your current knowledge and creative thinking, please develop a technical plan and design for an innovative project. The project must provide a solution to a real-world problem using the latest wireless networking technologies. Create a presentation outlining your ideas. Limit yourself to a maximum of 15 PowerPoint slides.

The presentation should be 10-15 min in length (10-15 slides) and targeted at your proposed project. The purpose of the presentation is to show the audiences that you understand the real problem and project vision, that you have identified the requirements for the project, and that you have proposed a technical solution to address the problem. Your presentation should include a general overview of your design, reasons for proposed wireless technologies, and how it meets the specified project goals and may discuss specific technical design issues or trade-offs that you have made in your design.
