Complex Network Structure And Security Analysis On FPGA IP Core

In recent years,due to its wide range of applications,complex networks have been favored by scholars from all walks of life,and have been widely used in various disciplines,such as physics,biology,electronics,etc.It not only provides us with a new perspective and new method to study the real network,but also raises the upsurge of using the complex network tools to analyze and study the actual network.In particular,after the complex network model such as scale-free network and small world network is proposed,the application of the complex network is developed rapidly in various reality networks such as WWW network,Internet network,linguistics networks,protein interaction network,film actor network,etc.Large circuit network including programmable circuit can be described by complex network,and in order to achieve programmable circuit optimization research,we use complex network tools to study the programmable circuit network,which is of great significance.This paper presents the complex network analysis of the FPGA IP core,including information extraction,calculation of Characteristic Parameters of Complex Network.In addition,we briefly introduce the complex network model,including random network,small world network and scale-free network,etc.On this basis,we analyze the type of complex network on FPGA IP core.Secondly,we analyze the security of FPGA IP core circuit network.First,we introduce the classic deliberate attack strategy,and then calculate the invulnerability measure of FPGA IP core circuit,and make the corresponding curve,analyze and compare invulnerability of different FPGA IP core under different attack strategies.Experiments on complex network show that,FPGA IP circuit network belongs to the Broad-scale distribution of the small world network;FPGA circuit networks belong to assortativeness or disassortativeness;experiments on invulnerability showthat,FPGA IP core is more sensitive to node removal than the ER random network;IB deliberate attack is more effective than ID,Random deliberate attack;FPGA IP core network with fewer nodes is relatively sensitive to node removal.
