ARM's TrustZone technology is the basis for security of billions of devices worldwide, including Android smartphones and IoT devices. Because TrustZone has access to sensitive information such as cryptographic keys, access to TrustZone has been locked down on real-world devices: only code that is authenticated by a trusted party can run in TrustZone.
Generally, TrustZone is used to access hardware-backed features and to perform sensitive operations in a supervised manner (e.g. cryptographic engine, credentials storage, etc.). Samsung heavily uses TrustZone for Samsung Knox, a system-wide security toolbox developed by Samsung. Sep 04, 2019 · Samsung Knox adds an enhancement called Trusted Boot, which goes a step further by taking snapshots during the boot process and storing the results in the TrustZone Trusted Execution Environment (TEE). Oct 23, 2018 · Samsung’s KNOX security software runs in the ARM TrustZone area, so it’s isolated from the rest of the system. Samsung Pay also uses ARM TrustZone to handle payment card information securely. On a new Pixel phone, the Titan M chip also secures the bootloader. The KNOX platform includes a number core features that address enterprise security needs: • Hardware Warranty Bit to prevent access to Samsung KNOX Container and prevents the Trustzone Key Store from releasing keys if an unauthorized kernel is detected. The Warranty Bit cannot be reset, even by reloading Samsung original binaries.
