Embedded Security for High Risk Areas with Multiple Fault Tolerant

Embedded systems have been almost invisibly pervading our daily lives for several decades. These Embedded electronic devices plays vital role in almost the areas of human life, Decreased costing, increased production tends to use these devices with higher reliability areas. They facilitate smooth operation in sphere of human life, avionics, automotive electronics, or telecommunication. New problems arise by increasing employment, interconnections, EMI, RFI, harmonics, sag, and end of course thermal problems. These problems are not quick common but expected always due to the fast growing multi utilize service like induction machine, radio frequency devices, rotating machines and much more. The challenges unique to embedded systems require new approaches to security covering all aspects of embedded system design from architecture to implementation. This paper presents a design of fault – tolerant embedded system by piggyback method of two embedded processor. Both processors are involved in adaptive sharing with software module. The customized fault tolerant embedded system is designed by combining selective protection on both hardware and software. Security processing, which refers to the computations that must be performed in a system for the purpose of security, can easily overwhelm the computational capabilities of processors in both low- and high-end embedded systems.
