Workshop I:

Mobile platform security architectures

Kari Kostiainen
Speaker: N. Asokan and Kari Kostiainen
In the past few years, there has been a dramatic increase in the popularity of the category of mobile phones commonly known as "smartphones". Consequently there is increased interest in the security and privacy research community in "smarpthone security". All dominant smartphone platforms, or more generally, mobile phone application platforms, incorporate platform security architectures that are widely deployed.
In the first part of this tutorial we will briefly explain the reasons why mobile platform security schemes have seens such widespread deployment and go on to discuss and compare some of them in more detail. Based on this analysis we will point out some open problems and possible future directions. In the second part of the tutorial we will present On-board Credentials (, a system that we have been developing over the last few years that makes it possible for developers to make use of existing hardware mobile security features to secure their applications and services.
