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 kartica: 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 primjer, 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.
The issuance of ordinary cards generally uses the method of encrypting the unique physical card number with the key.
Just like the ID card of the card reader, the SAM card and the card reader can be regarded as one, and the SAM card needs to be used for uploading, updating, and power-on confirmation of the card reader. SAM cards are generally installed on smart card terminal equipment, as the security control of smart card terminals, to achieve legitimacy authentication between terminals and cards, and can be widely used in urban One Card Solution, enterprise One Card Solution, identity recognition, security control, recharge, small purchases and other application fields.
