Abstract


Embedded systems with limited resources ( such as processing power , storage space , etc.) and special operating environment so that the security design and implementation is different from other general-purpose computer system . Limited resources , the system not only to complete the desired function , also supports encryption algorithm , security agreement or other safety requirements , this dual requirements so that the security of the embedded system design facing great challenges . This article briefly discusses the basics of embedded system security , including the challenges faced by the common hardware attacks embedded systems and common software security flaws and vulnerabilities , as well as embedded systems security design , research mainly based on the use of \reliable software attacks carried out by the program 's vulnerability or defect , analysis of the strengths and weaknesses of the defense technology and in-depth study of the two defense of such software attacks , hardware -assisted run security monitoring technology - code monitoring technology and data characteristics checking technology detailed and in-depth analysis of the design principles of these two technologies , mechanisms as well as their respective strengths and weaknesses , and on this basis its several improvement and expansion of ideas . Finally, we build the simulation environment SimpleScalar3.0 simulation of these two technologies , simulation and code performance monitoring technology , simulation results show that this technique can be enhanced embedded systems with small performance overhead program safety Executive .
