Abstract
The invention discloses a dynamic token. The dynamic token comprises an MCU, a crystal, a power source, an LCD and a button. The power source is connected with the MCU for supplying power to the MCU; the LCD is connected with the MCU for displaying a calculating password and working prompting information; the button is connected with the MCU for inputting information and switching on and switching off a system; and the MCU is used for being in charge of the working state scheduling, the working mode switching and the dynamic password calculating of the whole system. The dynamic token provided by the invention can be used to help a user to improve identity authentication security and protect the account security of the user. The dynamic token not only has the advantages of higher security, more functions and simple operation, but also is provided with a power-on password protection function, can effectively prevent identity theft, identity counterfeiting and identity fraud, and can provide powerful identity verification for users from various channels at any time at any place. Therefore, an authentication solution scheme which is convenient in use, complete in function and high in security and reliability is formed.
Description
Technical field
The present invention relates to a kind of dynamic token.
Background technology
Dynamic password is to generate a uncertain random digit combination according to the special SHA-1 algorithm in the world, and a password use is once effective, is widely used at present the applications such as Net silver, network game, telecom operators, E-Government, government of enterprise.Dynamic password is a kind of account anti-theft technology of safe and convenient, can effectively protect the authentication security of transaction and login, adopts dynamic password just without regular password, and safety is saved worry, thereby in this link of the most basic cipher authentication, has guaranteed the fail safe of system.Solution, because of the heavy losses that password swindle causes, prevents malice invader or artificial destruction, solves the invasion problem of being divulged a secret and being caused by password.Dynamic token is for generating dynamic password terminal.
Summary of the invention
The defect that the present invention seeks to exist for prior art provides a kind of dynamic token.
The present invention for achieving the above object, adopts following technical scheme: a kind of dynamic token, comprise MCU, crystal, power supply, LCD and button, and described power supply is connected with described MCU, and it is used to MCU that power supply is provided; LCD is connected with described MCU, for showing, calculates password and work information; Button is connected with described MCU, for the switching on and shutting down of input message and system; MCU, switches and calculating dynamic password for being responsible for operating state scheduling, the mode of operation of whole system.
Further, on described MCU, be also provided with programming and configuration interface module.
Further, described power supply is the button-shaped lithium-manganese cell of 3V.System needs clock to move all the time, for saving as much as possible power consumption, during token application, is mainly HALT mode of operation, and while not wherein being with LCD to show, when HALT pattern, system only needs 0.8uA.Through abundant Measurement and Computation, system can normally be used more than 5 years with CR2016 power supply, has guaranteed the service life of product.
Further, described LCD is 8 segment liquid crystals.This LCD drive current is extremely low, less than 1uA.
Further, described button is the young sheet single-point button of pot.
Further, the S1C17653 chip that described MCU is EPSON.This chip has large capacity program storage and RAM, and the several functions such as integrated LCD driving, RTC, UART, have extremely low power consumption, can meet the instructions for use of dynamic token.
Beneficial effect of the present invention: the present invention can be for helping user to improve identification authentication security, protection user's account safety.Not only there is the feature that fail safe is higher, function is more, simple to operate; Also possess startup password defencive function, can effectively prevent identity theft, falsely use and identity swindle, can be whenever and wherever possible for each channel user provides strong authentication, thus form easy to use, multiple functional, a safe and reliable authentication solution.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the function of the present invention.
Embodiment
Shown in Fig. 1, be a kind of dynamic token, comprise MCU, crystal, power supply, LCD and button, described power supply is connected with described MCU, and it is used to MCU that power supply is provided; LCD is connected with described MCU, for showing, calculates password and work information; Button is connected with described MCU, for the switching on and shutting down of input message and system; MCU, switches and calculating dynamic password for being responsible for operating state scheduling, the mode of operation of whole system.Wherein, on described MCU, be also provided with programming and configuration interface module.Described power supply is the button-shaped lithium-manganese cell of 3V, and LCD is 8 segment liquid crystals, and button is the young sheet single-point button of pot, the S1C17653 chip that MCU is EPSON.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
