A Research Of Security Methods In Commerce RFID Supervision System

In resent years, with the development of the science and economy, more and moreattention is paid to food quality problem, which causes some social and economic issues. So,how to take effective supervision and quality tracing is becoming more urgent to industrialand commercial administration. The old barcode tag technology can only recognize productcategory in food supervision. There is big deficiency in tracing food circulation. RadioFrequency Identification not only has advantage in technology but has the convenience innoncontact data reader. RFID is the development direction for the future identityidentification technology and the main technology to realize the sensor level in internet ofthings. As RFID technology itself has some security defects, the paper analyze the issues, aimto fulfilling RFID technology’s communication link and resists masquerader attacks such asMan-in-the-Middle attacks.The paper first introduces research background of RFID security technology, andanalyzes its overseas and domestic research status and adoptive method as well as itsadvantages and disadvantages. Then a conclusion has been drawn: data transmission’s linksecurity and illegal attack detection should be started with in considering RFID securityproblem. On the basis of the low computing ability of RFID system and wireless connectivityin reader and electronic tag, the paper presents an attack detection policy based on RSSlocation technology and RFID security authentication method based on elliptic curvecryptography. By comparing the coefficient of label signal strength at different stagesreceived by the reader in a safe condition and under attack, whether the RFID system is opento safety attack can be determined. On that basis, aiming at integrity, authenticity and security of information data and the by the way of the distributing the key of elliptic curvecryptography in asymmetric cryptosystem, the safety of RFID certification system can beensured.To test methods be achieved by simulation experiment and security analysis. Throughsimulation experiment in matlab7.1and by comparing the coefficient of label signal strengthboth in a safe condition and under attack, attack detection based on RSS location technologycan be tested. The simulation result proves the method is of high discrimination and validity.The paper analyzes the integrity, authenticity and security of information data by aiming atRFID method. Results show that the security authentication method can effectively defend theattacks of the common security issues.
