| With the development of science and technology and the enhancement of people’s public security awareness,electronic lock has gradually replaced the use of traditional mechanical lock with its advantages of rich key quantity and high security.With the development of technology,biometric identification technology and two-dimensional code technology are gradually applied in the field of electronic lock.However,due to the high cost of the system,and a large number of theft cases of simple electronic locks used in public places still remind us that electronic locks need to design relatively safe technical means according to the scene to prevent heavy losses.Therefore,based on the analysis and discussion of various electronic locks with high security,this thesis designs and implements a security scheme of dynamic cryptographic electronic lock system which is suitable for the promotion.The main research work of this thesis :(1)reviewed a large number of domestic and foreign research status of electronic lock,dynamic password and key management,and expounded the background and significance of electronic lock security research;(2)the technologies and application scenarios of various types of security electronic locks are analyzed and summarized,including relatively novel biometric identification technology and two-dimensional code technology;(3)the evaluation model of electronic lock security scheme based on AHP and TOPSIS methods is established;(4)designed and implemented a security scheme of dynamic password electronic lock system which is suitable for promotion,and proposed the security framework of the scheme.Completed the triple data encryption algorithm,dynamic password generation algorithm and key management system design,the system security implementation and the results of system testing and security analysis are also presented.The evaluation model of electronic lock security scheme established in this thesis is valuable for the industry.At the same time,the implementation and test results of the system show that the security scheme of the dynamic cipher electronic lock system designed in this thesis meets the requirements of security and low cost and is suitable for promotion. |
