1. a gate control system that generates and verify based on dynamic password is characterized in that comprising user side that generates dynamic password and the authentication end of verifying dynamic password;

  • Described user side comprises;

    Memory module is used for storage algorithm, key and dynamic factor;

    Dynamic password generation modules is used to use algorithm, key and the dynamic factor of described memory module storage to calculate dynamic password;

    Communication module is used for communicating with the authentication end, and the dynamic password that described dynamic password generation modules is generated sends to the authentication end;

    Update module is used for the dynamic factor of described memory module storage is upgraded;

    Described authentication end comprises;

    Read module is used to read the dynamic password that user side generates;

    The lockset module is used for opening or closing door lock;

    The certificate server module is used for client is authenticated;

    Wherein, described certificate server module comprises storage unit, authentication password generation unit, acquiring unit, contrast unit, communication unit, user profile library unit and transmitting element;

    Storage unit is used for storage algorithm, key and dynamic factor;

    The authentication password generation unit is used to use algorithm, key and the dynamic factor of described cell stores to calculate authentication password;

    Acquiring unit is used to obtain the authentication password that the authentication password generation unit calculates;

    The contrast unit is used to contrast the dynamic password that obtains and the authentication password of generation;

    Communication unit is used to authenticate communicating by letter of end and user side;

    The user profile library unit is used to store a plurality of user side information;

    Transmitting element is used for sending the door lock open command to the lockset module.
