Advanced Computer Networks / Mobile Security

Course Number 705010 and 705010 | Sommersemester 2020


This course is a seminar-style class which focuses on security aspects of mobile devices. We study the security mechanisms of smartphones and show how to employ them to protect sensitive information. Based on that, we analyze mobile applications regarding security-critical deficiencies, examine platform and application vulnerabilities and discuss how they can be exploited by attackers.

  • Security features of mobile platforms, e.g. Android, iOS, …
    • Access protection (PIN, Patterns, …), Secure Element, OS updates, permissions, sandboxing concept, …
    • Which mechanisms are provided in order to protect sensitive data?
    • How do they work?
  • Key and data storage on mobile devices
    • Device encryption, key derivation functions, key management, risks
    • Which kind of keys do you manage on your device?
    • In practice, what are the risks you have to cope with?
  • Using mobile devices for identity management
    • Mobile e-signatures, threats
  • Application analysis
