Hello. I am currently working on a Mesh Network using the Nordic Thingy53 board. As far as I understand, the Mesh protocol developed by Nordic already has encryption, obfuscation, authentication and replay protection built-in (as noted here https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/bt/bt_mesh/overview/index.html#ug-bt-mesh-overview-intro).
When we started working on this project we did not know that. Our goal was to compare encryption algorithms: therefore, I would like to know if there is any way to change the algorithm that is used by default, or any way to disable the current encryption so I can apply my own algorithms.
Thank you in advance and have a nice day!!
