AM623: How can I use the security hardware acceleration engine on Linux kernel?

Hello Hong,

- There’s one TISCI API for general binary blob signature verification supported by TIFS, but no primitive PKA services from TIFS.

What does this TISCI API specifically refer to? Is there any documentation available for it?

And Is there any example reference code available in the Linux SDK or MCU SDK?

Hello Hong,
In the Linux kernel, there is no corresponding TI SCI code implementation for TISCI_MSG_PROC_AUTH_BOOT.

In this scenario, how can I use PKA through TI SCI in the kernel?

Hello Hong,

Is the current SDK able to meet the requirement of only using PKA functionality under the Linux kernel, rather than under OP-TEE?

We currently only want to use the PKA functionality by invoking TISCI's API interface under the Linux kernel.

Hello Li,
There's no reference code in Linux kernel calling TISCI API TISCI_MSG_PROC_AUTH_BOOT.

Hello Hong,
Can I ask if TI can help provide an example program? The scenario of using PKA under the Linux kernel is quite common.
