Trustzone is a technology that OP-TEE is built on. As well, trusted-firmware fulfills secure boot. The OP-TEE model is a library of calls through the smc interface. A monitor mode handles this and dispatches to code in the secure world which has extended access right to memory. Often attacks are against errors in the API and not directly on the trust-zone infrastructure.

It is possible to host an OS in both the Secure and normal world with Trustzone. However, this is not a model supported by OP-TEE, which is a subset of the capabilities of TrustZone (and hence likely more secure).

How can I build OpenSSL for OP-TEE small trusted OS?

I want to build OpenSSL 1.0.2 for optee_os. But OpenSSL is very large and has a lot of dependencies(c library f.e.). OP-TEE has no c-library (and others). Can I build OpenSSL with only crypto algorithms? (without files, z-lib and so on).
