Embodiment Construction

[0014] refer to figure 1 , the traditional peripheral equipment add-in card 120 is made up of microprocessor 122 and nonvolatile memory 124, and microprocessor 122 has interface 126 to connect nonvolatile memory 124 in order to read and write the data stored therein, and microprocessor 122 can be replaced by an Application Specific Integrated Circuit (ASIC). Taking a microprocessor as an example, the host computer 100 is controlled by a peripheral component interconnect (Peripheral Component Interconnect, PCI) bus 110. The microprocessor on the peripheral add-on card 120 122 and exchange data with it. The driver program or application program 102 dedicated to the microprocessor 122 is loaded into the host computer 100 for execution after booting, and resets the microprocessor 122 through the reset signal RST# of the PCI bus 110 to activate the peripheral device add-in card 120 to work. Since the data in the non-volatile memory 124 is read and written through the interface 126...

Abstract

A method and system for protecting the software on additional card of peripheral is disclosed. Said method includes such steps as reading the encryped particular information from non-volatile memory by microcontroller when the first reset signal from peripheral bus is disabled, decrypting it, generating the second reset signal by microcontroller, receiving it by microprocessor, reading the decrypted particular information, transmitting it to host, recognizing and varifying it, and running the dedicated program of microprocessor to start said additional card.

Description

technical field [0001] The invention relates to the field of software protection methods, in particular to a technology for protecting software executed on an additional card of peripheral equipment. Background technique [0002] Generally speaking, the control chip on the peripheral device add-in card has a related driver or application program on the host computer to work with the operating system, so that the peripheral device add-in card can play the best function. In addition, the current chip design has developed towards multi-functional and systematic integration. In order to make the application meet the different needs of different customers, the control chips on many peripheral equipment add-on cards provide non-easy to read and write functions. The interface of the volatile memory, so that the driver or application program can instruct the control chip to read and write the necessary or customized specific data stored in the non-volatile memory through the interfa...
