CC1352P: TI AES Library for CC1352P

You can try to refer to aeskeyagreement example.

Ryan Brown1 & YiKai Chen: 

I have read the above-referenced documents.

& I am able to see the Encryption drivers are already included inside the CC13352P ZNP example.

Now,

I would like to know,

1. Which is the most secure & fastest encryption method out of AESCBC, AESCCM, AESCTR, AESCTRDRBG, AESEBC, AESGCM, ECDH & ECDSA?

2. Which one of them is suitable for UART Communication to secure communication?

I have give you another reference at https://www.embedded.com/how-to-secure-uart-communications-in-iot-devices/ . I suggest you to read it first to understand better about Symmetric and asymmetric security which is helpful on your choice and implementation.

YiKai Chen: 

I have read the document, Now I am cleared with the implementation.

I want to use asymmetric security with RSA public & private key implementation.

Now, will you please help me to know which driver listed above is suitable for my case?

We can only give you directions and guide. The implementation is on your own.
