AM2631: Does AM263x support TLS 1.2?

Part Number: AM2631

Hi, Expert

As title description, I know AM263x support TLS, but I don't what's version of TLS support.

Does AM263x support TLS 1.2?

I think we use MbedTLS 2.13.1 for TLS implementation, and it use software encryption without hardware acceleration, Am I right?

(https://software-dl.ti.com/mcu-plus-sdk/esd/AM263X/latest/exports/docs/api_guide_am263x/EXAMPLES_CPSW_LWIP_HTTPS.html)

Because I feel a little bit confuse, AM26x include HSM & SECURITY acceleration, but I am not sure this hardware security acceleration can support ethernet networking security.

I need some comment

May Thanks

Gibbs

    You can use DTHE to offload cryptographic operations. We have plans to release an appnote on offloading crypto operations on accelerator.
