I imagine it adds latency, which at the very least means more data is lost in case of accident, which can make it harder to know what went wrong.

It also adds an additional failure point, as a single bit error during encryption can scramble an entire data packet or worse, rather than just invalidating a single sensor reading.

You can do this with FPGAs in real-time.
