Simulation method and device of integrated circuit card, electronic equipment and storage medium

The invention discloses a simulation method and device of an integrated circuit card, electronic equipment and a storage medium, which can be applied to the field of network security or finance, and the method comprises the following steps: monitoring a serial port of a card reader in real time; when the current target message sent by the terminal through the serial port of the card reader is monitored, receiving the current target message; when the target instruction in the current target message is interpreted, obtaining a current data element fed back by the terminal and configuration content corresponding to the current target message in the configuration file; calculating the current data element and the configuration content by using a triple data encryption algorithm to obtain a current authorization request ciphertext; acquiring fixed data, transaction counter data and issuer application data corresponding to the message type to which the current target message belongs; splicing the current authorizat
