Joakim Bech talks about Linaro’s work in OP-TEE (Open Portable Trusted Execution Environment) small OS-like environment that sits aside a rich operating system, for instance Android. The purpose of the TEE is to keep all secret credentials and data manipulation in the small TEE rather than in a larger rich OS that is often the vulnerable target of malware and hackers in general. In order to reach this goal, application software is architected in a way such that sensitive functions are precisely defined and offloaded to the TEE in the form of Trusted Applications.
