Patrik Ekdahl is a Master Researcher at Ericsson in Lund, Sweden. He received his Ph.D. in Information Theory from Lund University in 2003. His thesis discusses analysis and design of stream ciphers and includes the co-authored work on the stream cipher SNOW which, in an adapted version, is the primary link encryption used in LTE. During the period 2004-2007 he worked for a SME in Lund, developing cryptologic equipment for the Swedish military and high end government institutions. He has been with Ericsson since 2007 where he has been  working at the security research department, mainly focusing on mobile device platform security from both a software and hardware perspective. During the last two years he has been involved in different standardisation organisations such as GlobalPlatform and their work on defining a Trusted Execution Environment for mobile devices.


Talk abstract: 

Upcoming security features in mobile devices

In this talk we will present a modern mobile device architecture with hardware based environment separation. We will discuss a general Trusted Execution Environment (TEE) and look more specifically into the TEE architecture as described by the standardisation body GlobalPlatform.

We will present some upcoming security services such as trusted user interface, remote connectivity from the TEE, and remote administration of trusted applications, together with the challenges we see for utilising these security features from a web server/browser.

Talk abstract: 

Who is the User?

The concept of user accounts is deeply embedded in many models of
computer and application use, but it is under assault from two directions:
first, user authentication is problematic for almost every internet user;
second, there is now often a many-many relationship between users and
devices/services, sometimes with minimal authentication requirements. In
this talk we consider the impact of trusted hardware upon these problems,
and ask whether we have the necessary building-blocks for solutions.
