Which is the best cryptographic algorithm to secure MAVLink protocol?

Question

I'm new in MAVLink. Now, I'm trying to check data loss between drone and GCS. After that I want to use one of the cryptographic algorithms to secure MAVLink protocol. Which one is the best?

Thanks & Regards

This question is pretty off-topic but since it's something I've touched before:

• You can look at the sMavLink protocol and implementation I made for smaccmpilot.org.
• You can look at the successor to Secure MavLink, "GEC", which has both an implementation and design docs I made for smaccm.
• You can look at the authentication-only solution proposed (implemented?) by the maintainers of mavlink. I don't really know much about that one other than it was in the works at one point.
