T6 is an open source operating system for Trusted Execution Environment(TEE) in mobile devices using ARM hardware security extension: TrustZone, which supports legacy operating systems(Android, Linux, etc.) to run simultaneously and provides a strong security property for the legacy operating systems. The design goal of T6 includes: small code base, secure boot and user interaction, multitasks, fault isolation, etc. We named it T6 because the kernel design follows the design art of XV6.
