Advanced RISC Machine (ARM) Trust Zone is a hardware and software security implementation architecture that provides a secure data execution environment. It splits the computer resources into two execution environments: normal execution environment and secure execution environment. Trust Zone can be implemented on different ARM architecture such as mobile devices that runs regular applications and architecture for micro-controllers. The main objective of the Trust Zone is to provide security for this architecture platform.
ARM architecture implements the trust zone using a split-environment processor that has different system IPs. The unique components can be used to enforce database security restrictions. The processors linked to the system database can be placed in a Trust Zone, excluding public access. In Trust Zone Hardware, where the hardware extensions are separated into secure and non-secure software, the secure world can be implemented as an operating system or a software library that handles database executions. This secure zone Bridge allows for secure communication between the CPU and peripherals (Ngabonziza, Martin, Bailey, Cho, 2016).
