Input nethod for password keyboard of self-service equipment in encrypted state and medium

Abstract

The invention discloses an input method for a password keyboard of self-service equipment in an encrypted state, which comprises the following steps of: defining two communication cables of the password keyboard, and defining one communication cable as an input cable, and defining the other one as a control cable; enabling the password keyboard to be in a plaintext input mode when powered up, andenabling a upper computer to switch between the plaintext input mode and a ciphertext input mode through the control cable; when the password keyboard detects user pressing, determining whether the password keyboard is currently in the plaintext input mode or the ciphertext input mode; enabling the upper computer to obtain information input by the user in a text input mode through the control cable according to a specific instruction; enabling the upper computer to start a main thread and to communicate with the control cable; meanwhile, starting a sub-thread to realize the acquisition of datainput by the user. According to the invention, the problem that the input data of the user cannot be responded to in time when the password keyboard of the self-service terminal processes the file acquisition or time synchronization command actively initiated by the server is well solved.

Description

technical field [0001] The invention relates to a method and a medium for inputting in an encrypted state of a password keyboard of a self-service device, and belongs to the technical field of self-service printing terminals. Background technique [0002] As a common and important device in the field of self-service equipment, PIN pad is widely used in self-service equipment. It is mainly used for inputting information such as user passwords, account numbers, and amounts; encryption and decryption and MAC operations; in the field of self-service equipment, PIN pads are often required It is used to encrypt the application message; the application message not only includes the message submitted by the user, but also includes the transaction initiated by the server (such as system time synchronization, terminal file acquisition, etc.); when the server initiates an active transaction , the encryption of the message will use the password keyboard. If a user comes to the terminal ...

AI Technical Summary

Problems solved by technology

[0004] (1) Suspend the user's input, but only after the password keyboard encryption operation is completed, the input can be performed. In this case, the normal operation time of the device is reduced. When the user uses the keyboard at this time, the interface does not respond at all, giving the user a keyboard fault misunderstanding;

[0005] (2) The user can input, but after the password keyboard encryption operation is completed, the relevant input information is returned to the application. Very bad user experience
