Design Of Information-Leakage-Prevention VGA Transportation System Based On Bit-Plane-Divide Processing

With the wide application of computers, many researchers have focus on the problem of information safety which is caused by the information electromagnetic leakage of computers. As the foundation of EMC traditional methods are, such as wave filter, electro-magnetic shield, disturbance signal and so on, so that useful information electro-magnetic leakage may be prevented. This paper presents a new kind of design association with non-information leakage attribution of DMD display and of parallel transportation. That is Information-Leakage-Prevention of VGA Transportation System Based on Bit-Plane-Divide Processing. This paper introduces the mechanic structure, operation electronic control principle, and its non-information leakage attribution of DMD display. After confirm the main information leakage resource of computer is VGA transportation line, this paper deals with the model of far away distance square wave electro-magnetic radioactivity, and get some conclusions by simulating in MATLAB. Based on the results of simulating ,this paper presents a new kind of anti-information-leakage transportation system and accomplish the software and hardware design of this system, VerilogHDL for the software design and FPGA for the hardware design as its processing core.This research is characterized by interdisciplinary across of mechanics, electronics, optics, control and detection. The achievements can be widely use in the field of high information safety level such as military and business.
