Research On Program Hiding Technology Based On Motherboard Firmware

With the rapid development of information technology, distributed denial of service attack, hackers and other network crime has been severe. Through electronic forensics technology crackdown on Internet crime has become an important means. But how to ensure that the electronic forensics software can "permanent" stay at target computer is an urgent problem to be solved, program hiding technology direction how to solve the problem.Discusses the current situation and development trend of the program hiding technology, describe the elementary knowledge and key technology of the program hidden system based on mainboard firmware involved. Introduces the basic input output system, computer start-up process, interrupt handling program execution procedures, interruption to scale hooks technology and driver programming technology.Given the program hidden system based on mainboard firmware design idea and design principles, puts forward design program hidden system in the main problems needing attention, painted the whole system structure. Completed the implant module, guide module, industrial standard system structure module, driver module and download module design.After the design of program hidden system based on mainboard firmware, discussed the implant module, guide module, industrial standard system structure module, driver module and download module concrete realization, test and analysis the performance of the system.Test results show that , target program can be hidden by the program hidden system based on mainboard firmware, and the computer system can work stably.
