The ARM® TrustZone® API provides an industry standard for applications to access security features. Applications written for a platform implementing the TZAPI can be transferred easily to other platforms: - Independent of host operating system
- Independent of hardware platform
- Based on security standards such as PKCS#11
- Strongly typed to promote secure implementation
- Synchronous and asynchronous
- Independent of TEE implementation
- Promotes efficient bulk data transfer
The TrustZone API may be used royalty free to implement Trusted Execution Environments and the specification is available for download here. Back to Top |
