摘要： Key diversification is performed during a mutual authentication between a SAM integrated circuit (IC) card storing a master key, and a user IC card storing an identification number. The user IC card is connected to the SAM IC card through a communications interface. The key diversification includes deriving sub keys from the master key, and computing ciphered strings through corresponding cryptographic computations on a string obtained by an elaboration on the identification number with the sub keys. A diversification key is generated by linking together a combination of bytes of the ciphered strings.
