MSP430FR6820: TLS library or middleware for secure key exchange ?

AnBer

Part Number: MSP430FR6820

Team,

For an MSP430FRxxx + CC1xxx application:

It seems that for MSP432 the mbed TLS lib can be used:
https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/795099
I know that TLS is suppose to use TCP/IP but I am looking for something comparable for sub-1Ghz wireless without TCP/IP SW layers.
-What are the options for MSP430FRxxx for TLS 1.3 or comparable for Wireless type of network (MSP430FRxxx + Sub-1Ghz CC11xx)?
-Do we have for example third party offering this?

-Regarding the http://www.ti.com/tool/MSPBSL It seems that we have drivers for AES128 accelerator.
Do we have some collateral on how secure key exchange can be implemented?
Do we have middleware that could support secure key exchange for sub-1Ghz wireless network?

Thanks in advance,
A.

Hey AnBer,

There is no TLS lib for MSP430 and I'm going to ask the Sub-1GHz team to comment on something comparable for a Sub-1GHz network.

As for the AES128/AES256 accelerators in MSP430, I couldn't find much collateral speaking about secure key exchanges. There is this white paper giving a very high level overview of MSP430 security features. I would say that in most cases for MSP430, Keys are stored at time of production through a process flow that the customer has deemed secure and acceptable. Some MSP430's also offer secure/encypted Bootloading, so it could be possible to use this to update keys, but the key for the secure bootloading would already need to be programmed in.

Thanks,
