Embodiment Construction
[0105] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.
[0106] The embodiment of the present invention provides a method for implementing a dual-purpose device sharing a display screen and buttons. The dual-purpose device described in the embodiment of the present invention includes two parts: a dynamic token module and a USBKey (smart key module). The card module and the USBKey are physically connected through an interface. When the dynamic token module in the dual-purpose device is triggered by power-on, receiving electromag...

The invention discloses an implementation method for sharing display screens and keys in dual-purpose equipment and belongs to the field of information security. The method includes resetting a dynamic token module prior to starting global interrupt, calling a master function to perform a master cyclic process, and initializing the system state into a hibernation state; judging the type of interrupt when interrupt is detected; setting a communication wakeup mark and resetting a communication interrupt mark if the interrupt is communication interrupt; setting a key wakeup mark and resetting a key interrupt mark if the interrupt is key interrupt; setting a real-time clock wakeup mark and resetting a real-time clock interrupt mark if the interrupt is real-time clock interrupt; judging the type of the wakeup mark when the fact that the wakeup mark is set is detected; performing communication processing if the communication wakeup mark is set; performing key processing if the key makeup mark is set; and performing real-time clock processing if the real-time clock wakeup mark is set. The method has the advantage that sharing of hardware resources by the dual-purpose equipment is implemented.
Description
technical field [0001] The invention relates to the field of information security, in particular to a method for realizing shared display screens and buttons of dual-purpose equipment. Background technique [0002] The smart key device is a hardware device with a USB interface. It has a built-in single-chip microcomputer and a smart card chip, and has a certain storage space, which can store the user's private key and digital certificate. Identity authentication; dynamic tokens are terminals that generate dynamic passwords. Dynamic passwords are a safe and convenient account anti-theft technology that can effectively protect the authentication security of transactions and logins; in order to achieve multi-functional applications, smart key devices and dynamic The token is integrated in one product, but the smart key device and the dynamic token are two independent devices with different buttons and displays, which will cause inconvenience to users.
