With the popularity of computer networks , the application of information technology in all areas of society today , more and more in-depth . In this social environment , the growing popularity of office automation , office areas , the increasingly widespread application of electronic documents , and bring a lot of convenience . But at the same time, this new office , security and the authenticity of the documents is also growing cause for concern . In this context , the e-signature technology is put forward . In the field of computer applications , through electronic signature to ensure the security of electronic documents has become the hotspot of research and solved . USBKey built - in smart card chip , the critical information stored in USBKey security protection can be provided directly from the hardware level . USBKey using the USB interface, small size , easy to use . In order to ensure the safety of the user 's personal certificate , we take advantage of the good performance of the USBKey storage and password , the private key and personal certificate stored in USBKey on , effectively to ensure that critical information completely and only . More in line with the document approval often need more than consultation paper in USBKey into multiple signature technologies , combined with the ActiveX control technology and electronic signature system . Papers useful to explore how to effectively ensure the security of the stamp , which ensure the security of the documents , and has a high practical value . The paper consists of six parts , the first part of the background and significance of this study were presented and introduced electronic signature technology research status ; second part describes the knowledge of cryptography , middleware technologies , digital signature technology , PKI the technology and USBKey technology for the application of the back provides theoretical support ; inadequacies of the third part of the three current application range of traditional electronic signature system , solve the electronic signature security issue , application combined USBKey and ActiveX controls , and digital signature technology, design solutions ; fourth part of the combination of the first part of the key technologies , the design of the electronic signature system ; fifth part of the program of each functional module detailed description ; sixth section gives application examples of the system , the system was tested .
