Method and system for quickly making out invoice of tax control dedicated equipment based on embedded platform

Abstract

The invention discloses a method for quickly making out an invoice through tax control dedicated equipment based on an embedded platform. The method comprises the steps that multiple security chips and single tax control equipment are identified by operating the scheduling program; the key derived from the tax control equipment is stored in multiple security chips through the scheduling program; the request of making out the invoice is monitored through the scheduling program, and the scheduling program acquires the request of making out the invoice and then allocates the request of making outthe invoice to the security chips which currently do not perform encryption / decryption operation of multiple security chips; and encryption / decryption operation is performed on the acquired request of making out the invoice through the security chips which currently do not perform encryption / decryption operation, and the encryption / decryption operation result is returned to the scheduling program. According to the tax control dedicated equipment based on the embedded platform, the security chips are scheduling to perform the data request of making out the invoice of the same tax number and perform concurrent processing so that the encryption / decryption operation speed of making out the invoice can be enhanced, and the secure and efficient solution is provided for the tax control dedicatedequipment of the system for making out the invoice.
