| In the last year, from the global range the expense because of the security questionhas raised geminate .The development of the close computer network turning to opennetwork and the operation from the simple data traffic to network trade make theinformation security to new development .Adapting to the global normalization, ourcountry start the information security authentication in due for according tointernational tradition in 1997, and in the end of 1998 the information securityauthentication system has been founded. The important thing in developing electricbusiness is ensuring the data and information transmit security. After several years′development, a suit of information security settling object is coming into being. That isPKI (Public Key Infrastructure). Crypto technique is the key of information security.Security in network, especially in Internet application, needs the sustention of PKI.The paper introduces the design and performance testing of the softwareauthentication USB key based on PKI technology system. In the end of the paper theperformance testing results are given .The soft wares of the product include the USBkey application software data ,encryption and data decryption ,identity authentication.In the 1 chapter , the paper introduces the backdrop and the development inside andoutside;in the 2 chapter the main is the development ,compose and concept implementprocess of the PKI technology system .In the 3 chapter , the paper introduce the productcollectivity design ,include of USB technology and the manufacture design,thehardware ,software ,order information structure using in data exchanging .The paperin the 4 chapter introduce the functions and the manufacture performances, includingthe digital signature ,identity authentication ,the software and hardware performancestesting .In the last chapter, the paper gives the conclusion and some amelioration advice.In order to test the manufacture performances, we write the good test programmed.After testing in some operating systems ,the application software --User managerapplication is normal ,we can apply,query ,import,export ,delete the certificates;The user can incept and send the email with the digital sign and encryption with thecertificate .In the end, the paper gives the conclusion and some amelioration advice. |
