On-board Credentials (ObC) was a project carried out at Nokia Research Center from 2005 to 2013. The vision behind ObC was to safely open up the hardware-based trusted execution environments, widely deployed in smartphones since early 2000s, so that it can be used by ordinary application developers. ObC technology was transferred to Nokia Devices business units and was deployed on all of Nokia Symbian Belle devices and Nokia Windows Phone 8 devices.
Work in the general area of mobile trusted computing continues in our Secure Systems group, partially supported by ICRI-SC and other industrial partners in the Helsinki area.
