Course Overview

This course covers aspects and principles of network security. Based on many attacks on common technologies used in communication systems, this course illustrates how things can go wrong and provides basic measures to protect a network from mistakes committed in the past. It covers furthermore the fundamental concepts of security and security problems.

Areas covered in this lecture:

• Physical and Link Layer Security
• Network Layer Security
• Transport Layer Security
• Application Layer Security

Please note that it is strongly recommended to attend communication systems first since it provides the background knowledge for this lecture.

Topic

This year's project will be about Bluetooth Low Energy (BLE) security. BLE is a part of the Bluetooth communication technology, designed for embedded devices with local connectivity and low data rates.

Many "smart" devices, available in every tech-market, are controllable via BLE. Often the security of those devices is insufficient. We plan to get some of these devices, analyze their security, create an application to control the device and break the security.

 Official module entry: [89-4245] INF-42-45-M-7 (old module nr: INF-42-45-L-6)

Requirements

• Programming knowledge is required (we will use Android Studio Java/Kotlin).
• Lecture "Communication systems" is required.
• Lectures "Network security" and "Protocols and Algorithms for Network Security" are recommended.
• ... You should be interested in security.

Organization

It will be a group project. It is planned to have group sizes of 2 to 4 people.

Recommended Readings

• With Low Energy comes Low Security
• Analysing Characteristic Securityon BLE Peripherals

Course Overview

The objective of this lecture is to introduce the art of performance-related modeling of distributed systems. We will use worst-case assumptions in order to obtain robust results.
