1. an intelligent cipher key equipment, comprises MCU, it is characterized in that:

  • also comprise input unit and display unit, and described input unit, display unit are connected with MCU respectively;

    Described display unit comprises display device;

    If described MCU part directly and main-machine communication, then can not be used for being connected with main frame in MCU setting and assist MCU to complete the interface unit of communication;

    When described intelligent cipher key equipment receives the application requests of from host, data input is carried out by display unit display password prompt code prompting user, described data are PIN code or key message, the data of user'"'"'s input are obtained by input unit, described intelligent cipher key equipment judges whether it is checking PIN code according to the data of input, being that then equipment is interior performs the verification of user'"'"'s PIN code, be proved to be successful, continue to use intelligent cipher key equipment to carry out other operations of being correlated with, authentication failed then can not work on;

    Otherwise described intelligent cipher key equipment is used as the application of network entry, and the key message obtained by input unit is sent to main frame by described intelligent cipher key equipment, and key message sends to network far-end to be used for logging in network by main frame;

    Or described intelligent cipher key equipment passes to main frame to after described encrypted message key, main frame sends to network far-end to use again;

    Or described intelligent cipher key equipment does not deal with and sends to main frame to be encrypted by host side described key message and then send to network far-end to use;

    When described intelligent cipher key equipment receives the use of host request to equipment, data are inputted by input unit by display unit display reminding user, after intelligent cipher key equipment receives the input data of input unit, encrypt data or send to main frame after recompile process, main frame has had the operation of the laggard line correlation of the described data processed;

    The secret rule that certain user and equipment are observed jointly is there is between the prompting of described display unit and correct PIN code, namely the information of display unit display is not the data that user will input, the computing rule that intelligent cipher key equipment adopts and user arranges, to information inverted order, or XOR, data are processed, then as the reminder-data of giving user, user does corresponding change to data thus obtains the information that user should input after obtaining information, then the information that this newly calculates by user inputs to the data that intelligent cipher key equipment verifies as PIN code.
