Abstract
Wireless communications are pervasive and have been used for a century. They are used in a very large set of security applications (communications by security forces, car key remote, alarm systems, access control, drone command and control, and surveillance devices). However, day-to-day applications also require to be protected for privacy and personal security, such as WIFI or mobile communications (2G/3G/4G). At the same time several challenges are present in wireless communications security, for example, messages are broadcasted, making it possible to intercept them without being noticed. Wireless signals are subject to jamming, making them unavailable.
This course will give a large perspective of the fundamental challenges in securing wireless communications, from the physical layer, and modulations to the application protocols. A special focus will be put on practice with hands-on exercises (using software-defined radios and WIFI dongles).
Teaching and Learning Methods: The course is composed of lectures, Labs and small projects with a final presentation.
Course Policies: Class attendance and labs.
None.
There are no formal requirements but it is recommended to have a background in radio engineering and security (reminders will be made). Students who can are recommended to take “System and Network Security” (SysSec), “Secure communications” (SecCom) and “Radio engineering” (Radio) courses.
The course is made of 6 3-hours long lectures, 2 labs covering the following topics:
-
Introduction to wireless security
-
Reverse engineering radio protocols
-
Software-defined radio lab
-
Bluetooth security
-
WIFI security
Learning outcomes:
- Analyze the security of a wireless system
- Identify potential problems and perform pen tests using wireless communications.
- Participate in the design of secure wireless communications systems.
Nb hours: 25,00
Evaluation:
-
Grading is based on lab reports (30% of the final grade)
-
Written exam (70% of the final grade).
