TLSSocket Using Secure Element

Mbed OS
,
1

Hello,

I’ve a custom cloud client implementation, where I use a TLSSocket to establish a MQTT network connection.
My mbed-os device does the following:

  1. Generates a rsa-keypair using the mbedtls library,
  2. Creates a CSR using the keypair
  3. Sends this CSR to the cloud using a secure restful api
  4. The restful api returns a client certificate.

By using the self-generated private key, client certificate received from the restful api, and hard-coded CA, we establish a MQTT network via TLSSocket.

How can I use a secure element (like atecc608a or infineon optiga-x) to increase the security of my device, base on my TLSSocket use case described above?
