Abstract

The invention discloses a card reader and card reader safety certification method, device and system belonging to the field of data safety. The card reader comprises a data transmission module and a safety certification module, wherein the data transmission module carries out data transmission with a terminal and / or an external card and sets a data encryption algorithm and a certification algorithm for certification; and the safety certification module is connected and communicated with the data transmission module and the terminal and sets the data encryption algorithm and the certification algorithm for certification with the data transmission module and / or the terminal. The card reader safety certification method, device and system enhance the safety of communication and the reliability of the card reader through the certification before a conversation and enhance the confidentiality of data through the encryption during the conversation.

Description

technical field [0001] The invention relates to the field of data security, in particular to a card reader, a card reader security authentication method, device and system. Background technique [0002] A card reader is a device that can exchange data with smart cards, memory cards, or other types of cards. The card reader is connected to the personal computer through USB or other serial ports, and can exchange data with the personal computer, but both receiving and sending data need to follow the data communication protocol of the card reader. [0003] The card reader is a data transmission communication module, which is responsible for receiving data from the terminal (such as a personal computer or other electronic equipment) through a certain data communication protocol format, and transfers the data according to the data communication protocol that the card connected to the card reader can receive. Format, reorganize the data and forward it to the card; otherwise, afte...
