How do you know that the AES instruction set on your device's processor doesn't include a backdoor? Sure, the algorithm is public, but how do you know how it was implemented?

AES starts with 16 bytes and then encrypts it to 16 bytes. So there is no good place to hide extra data. Even a single bit that did not meet the AES spec for the key in use would produce complete garbage at decryption. So attempts to leak the key would at least leave a mark.

Unless it’s a timing based leak..
