Research And Implementation Of Authentication Mechanism Based On USBKey

The ID authentication service is important to the security of information system in the open environment.It is the premise and foundation among all the network security services.With the development of internet,especially the appearance and the rapid development of electronic commerce,information security has been the focus of society.In particular,information security under network environment has influenced the national security,the economic development and the social stabillity significantly.To reasearch and develop different ID authentication systems to suit to various network environments,which is of great importance.From the research comparing to all kinds of ID authentication technique,we have further understanding to the ID authentication system under network environment and have some ideas that some attacks may occur to the authentication system,realize that USBKey is a economical and convinent platform,it can be used in netowrk security authentication, and it has double security with PIN and USBKey,so we can begin our research from this aspect.After research the defects of the ID authentication based on USBKey in the network environment,according to the feature of ID authentication system in the network under the real application situation,we integrate the SHA-1 and ECC algorithm and analysis them deeply in designing the ID authentication machanism based on USBKey,new authentication machanism is different from the old PKI system with RSA and MD5,it use the shock response model,"one time padding" mutual authentication, it can improve the security and intensity,lower the algorithmic complexity,increase the operating efficiency of the encryption and decryption algorithm.Lastly,this paper research the ID authentication tech with cipher and hardware token,finish designing ID authentication mechanism based on USBKey,and realize the application interface and mechanism,through the simulaton experiment,this mechanism reach the target basically.To foresee,the ID authentication tech will be used in life and work more widely.Because time is limited,we just do some research to the ID authentication technique based on USBKey.We still have many things to study and the ID authentication system can be improved further,Digital certificate may support ID authentication well,we can study the authentication mechanism byusing digital certificate.The ID authentication tech thoery and expirement has a lot of things to research deeply.
