Abstract

The invention discloses a data processing method for an ATM machine-core encryption and decryption device. The machine-core encryption and decryption device plays an isolation role between a machine core and a host. After the whole machine is powered on, the host sends a verification request to the machine-core encryption and decryption device and after the machine-core encryption and decryption device replies and responds, the machine-core encryption and decryption device sends a verification request to the host. The host can access parameters and state values of a machine-core device only after the machine-core encryption and decryption device confirms normality, so that money withdrawing and money depositing operations of customers in an ATM transaction and maintenance-type operations such as money replenish and machine cleaning and the like of maintenance personnel of the whole ATM are realized. The data processing method for the ATM machine-core encryption and decryption device adopts a dual-party verification mechanism and has characteristics of wide connection capability and expansion capability and high flexibility and effectively improved security of the ATM.

Description

technical field [0001] The invention relates to the technical field of encryption, in particular to a data processing method of an ATM core encryption and decryption device capable of effectively improving the data security of the ATM machine. Background technique [0002] With the widespread use of financial self-service terminals such as ATM machines, as the core equipment of ATM machines, the security of banknote processing modules (ie movement) has attracted more and more attention from customers, banks, and regulators. There are corresponding safety regulations on the machine installation. However, the banknote processing module and the host usually use transparent plaintext for data transmission. Most applications directly refer to the communication protocol of the movement manufacturer for communication and state control of the movement components, and all use the interfaces provided by the movement, such as RS232, USB interface. [0003] However, the movement has t...
