## Description

Hello

Is there a way to protect my model after converting it to an Engine file?  
Assuming I want to deploy it on an edge device, I want to make sure that if anyone (in any case) accessed the model file will not get any info about the model or use it.

Hi @mhk50,

This is out of scope for TensorRT, but you are free to encrypt the engine file with any technique you like and decrypt back before feed to TensorRT when needed.

Thank you.

Assuming that you want to encrypt the engine, where can you store the symmetric key to do that? Can you leverage a fused key?
