The SAM card (Secure Access Module) is the core of security control in smart card application systems. A SAM card is a special CPU card that stores the key and the encryption and decryption algorithms.
There are many types of SAM cards:
PSAM kartice: terminal security control module, generally used for micropayment deduction.
ESAM: A manufacturers (system) SAM card used for authentication of devices.
ISAM: used to recharge.
In the specific implementation, it will be more diverse. na primer:, some devices are authenticated not with ESAM cards, but with dedicated modules. As a result, there is the problem that keys are implemented in software, and there may be key leakage, and one way to solve this problem is to store multiple sets of keys and specify one set of keys in a random number.
Pri izdajanju običajnih kartic se praviloma uporablja metoda šifriranja edinstvene številke fizične kartice s ključem.
Tako kot osebna izkaznica čitalnika kartic, kartico SAM in čitalnik kartic lahko obravnavamo kot eno, in za nalaganje je treba uporabiti kartico SAM, posodabljanje, in potrditev vklopa čitalnika kartic. Kartice SAM so običajno nameščene na terminalski opremi pametnih kartic, kot varnostni nadzor terminalov pametnih kartic, za doseganje legitimne avtentikacije med terminali in karticami, in se lahko široko uporablja v urbani rešitvi z eno kartico, Enterprise One Card Solution, prepoznavanje identitete, varnostni nadzor, ponovno polnjenje, manjši nakupi in druga področja uporabe.
