An authentication method based on a multifunctional security authentication terminal

Abstract

The invention discloses a multifunctional security authentication terminal and an authentication method based on the terminal. The terminal comprises a main control unit, wherein the main control unit is connected with a card reader unit, a hardware secret key area unit, a keyboard unit, a display unit and multiple communication units respectively. The method comprises the following steps of obtaining a user name and a password for correctness validation; after receiving a successful validation result by an entry terminal, obtaining a terminal number from the security authentication terminal, and sending the terminal number to a transaction information server; sending an encrypted working key and validation data to the entry terminal by the transaction information server according to the terminal number; requesting the security authentication terminal by the entry terminal to implement validation on the working key; implementing validation on the correctness of the working key by the security authentication terminal. By applying the authentication terminal provided by the invention, a security authentication function and a card reading function can be realized; the authentication terminal is diversified in function and high in communication compatibility; with the authentication terminal, a user can operate or use quite conveniently; the terminal and the method can be widely applied in the financial field.

Description

technical field [0001] The invention relates to security information processing technology, in particular to a multifunctional security authentication terminal and an authentication method based on the terminal. Background technique [0002] In traditional security authentication methods, it is usually realized by using a USBKEY, a security authentication terminal. The USB Key is a hardware device with a USB interface. Therefore, the USB Key can only communicate with other devices in the USB communication mode. When the user uses a device without a USB interface to log in to the network, he cannot Using the USBKey for security authentication brings great inconvenience to the user. Moreover, the USB Key can only realize the security authentication of login, and has a single function. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a multi-functional security authentication termi...
