An Introduction
This system is a new access control security product successfully developed by Zhongda Microelectronics based on CPU card, which is different from the previous access control system. The high security access control reader is equipped with a PSAM card, and the user card used with it is a CPU card. The high security access control key system is based on the high security features such as non-copying (the key can only be written but not read), not afraid of monitoring (data transmission uses ciphertext), and not afraid of tampering (using MAC to verify data integrity) The designed access control key management system. High security access control system is widely used in government agencies, military, banks, medical and other fields because of its high security characteristics.
