The Research On Key Techniques Of Electronic Signature Based On Multi-system

Currently, there are severa l different types of electronic si gnature systems on the market, in most of these electronic signature sys tem s for offi ce automation software(such as Office, WPS, Free Office, etc.), although these sys tems to achieve the signa ture, but t here are some of t he defe cts: for example, Office signatur e fil es can not be completed in the WPS environm ental document validation and si gna ture verification, the same, Office documents can not be completed signature docum ent vali dati on and signature verifica ti on environm ent under W PS, though WPS sys tem and Office systems are com pati ble. This requires constantly develop different signa ture systems to deal wit h different appli cation software, while a gre at deal of appli cation office software mai ntenance costs. So the study for the multi-sys tem compatibl e, stable, reliable electronic signature sys tem is very important.To solve these problems, thi s research- oriented mul ti-system mixing signature technology, which is based on COM technology, digital si gnature, public key infrastructure(PKI), encr yp tion technology and other technologies as t he theoretical basis, multi-appl ication environment signature and each signa ture is carried out independently of each other. The main researc h work incl udes:1) S tudy based on COM component for multi-sys tem electronic signature sys tem archi tecture, gi ves mixed signature model based ActiveX controls, research-ba sed signa ture controls transparent double buffering technology to solve multi ple appli cations under signature stabi lity issues. In order t o use the signature stamp can be like living in the same display can be transparent; Finally, based on Public Key Infra structure(PKI) electroni c s ignature technology to solve the electronic seal and electroni c signature security, uniqueness, integrit y and non-repudiation and other issues.2) The development of electr onic signature based on PKI, st udied t he automation of office software Word / WPS secondary development interface, realized for Word /WPS electronic signatur e applications including tool bar assembly, signature component modul e controls and parameter set tings.Through the electronic signature sys tem for multi-sys tem research, users can compl ete any environment under a cover under seal, document signing and si gna ture verification and other acts in Word / W PS, t he entire sys tem has been tested and is stable, reliable, and that for mult i-system elect r onic signa ture model can be appl ied t o e-com merce sys tem s and e-government among systems.
