I'm not a Lua expert, but from what I understand, you have the following
options:
1. Bundle Lua and your script on the flash drive.
The script is easily tamperable.
2. Bundle Lua and a pre-compiled script (using luac).
The script is not easily tamperable.
3. Write a C program and link it with the Lua library,
and invoke Lua from within the C program.
Now you can just provide the one C program on the flash.
