Design And Implementation Of Multiple Protocol Special Reader Based On OMAP-L138

With the development of technology,while the IC card is popular in our life,the security of IC has been widely concerned and the security analysis of IC card has become one of the research focuses.Among them,side channel attack method is one of the most important methods of IC card security analysis.This project aims to design a multi-protocol dedicated reader that used for side information acquisition of IC card,including the contact smart card reader based on ISO7816 and contactless smart card reader based on ISO14443,and complete the acquisition and processing of power consumption information and electromagnetic radiation information.This paper first elaborates the background and significance of the research work,and introduces the research status of the security detection reader at home and abroad.Then it introduces the theory of reader system,mainly including ISO7816 protocol,ISO14443 protocol,radio frequency identification principle and acquisition technology of side information.Then this paper completes the circuit design of the special reader system based on the OMAP-L138.This part firstly gives the total design of the reader system.Then it completes the OMAP-L138 system circuit design,multi-protocol reader circuit design and system design of power measurement respectively.Among them,the design of multi-protocol reader circuit includes the design of contact reader circuit,the design of the contactless reader circuit and the design of RF antenna.In the design of power measurement system,it firstly completes the power consumption information measuring circuit design of contact smart card,then it analyses model of the contactless smart card power consumption information.After that,this paper gives the circuit design of the power consumption information acquisition front-end analog filter and gives the final simulation results.When completing the hardware design,it starts to test the hardware function of the OMAP-L138 system.And the test results show that the OMAP-L138 system can work normally.After the design of hardware,this part finishes the software design of the reader system based on the OMAP-L138.This part firstly gives the overall design of the system software,then completes the Linux kernel porting,contactless reader software design,contactless reader software design and communication interface design respectively.In the end,this paper gives the general realization of the system software.At the end of this paper,it starts the total test for the reader system.Firstly,it tests the basic functions of the contact and non-contact reader,and gives some performance tests for the reader system,and the results shows that the reader system can complete the common operation of the smart card.Then the reader system are used in the acquisition platform of the power consumption information,and this paper completes the test for the power consumption information acquisition.The test results show that the reader design satisfies the design requirement of the special reader for side information acquisition,and it can be used for the IC card information acquisition platform.
