* Trusted Execution Environment (TEE)
The TEE is a secure area of the main processor in a smart phone (or any connected device) that ensures sensitive data is stored, processed and protected in an isolated, trusted environment without an extra Bill of Material (BOM) cost. The TEE’s ability to offer isolated safe execution of authorised security software, known as ‘trusted applications’, provides end-to-end security by enforcing protection, confidentiality, integrity and data access rights and by providing means for strong user and device authentication. In particular, the TEE offers a level of protection against software attacks running in the Rich OS environment. It houses business-specific sensitive applications, which need to be isolated from the Rich OS.
