Abstract

ARM TrustZone is an emerging embedded security technology based on the split of a system into a secure and normal world. Currently a number of System-on-Chip platforms exist, which include support for ARM TrustZone. Unfortunately relatively little work has been done on open-source software for TrustZone systems. In our belief this is partly caused by the lack of cost-efficient development boards, which allow access to ARM TrustZone features. This paper discusses experiences made by the authors with a rather inexpensive development board and shows how system-level development on TrustZone-enabled hardware is possible in class-room settings.
