sam = Secure Access Module
sim = Subscriber Identification Module

Both sam and sim store the key
Sam's key can calculate and verify the ciphertext of the user card
The sim card key is used to generate the identity authentication ciphertext.

An inappropriate example: sam can determine whether the ciphertext generated by sim is correct.
