Research On Form Signature Architecture Based On SSL

Taking the research and development of Integrated Electronic Commerce Software GECIS as background, this paper brings forward a framework model of Form Digital Signature based on SSL protocol to provide higher security guarantee for EC.The whole task penetrates the developing process based on 3-layer architecture.It uses architecture methods and technologies such as Design Pattern ect.Moreover, it integrates UML and ACME to establish software models.Firstly,An applying architecture of SSL protocol is given.Then the security algorithm system and technology specification is analysed and researched.According to this , the security advantage and existing problem is discussed.Moreover,the repairing measure and the implementing strategy of SSL is put forward.Secondly,the theory of Digital Signature and the DSA algorithm is discussed.Mainly,the mathematics model of DSA algorithm is analysed and proved , and the improved model accord- ing to the specific application of DSA is given.Then, the Form Digital Signature model is analysed and designed on the domain.In the phase of domain analysis,the requirement of Form Digital Signature is abstracted and described, then use case model and activity model are created.In the phase of domain design,based on the method of object/component oriented ,object structure model and object behaviour model of Form Digital Signature are created.Also the Design Pattern is used to optimalize the design.At the end of this paper, the configure process of the SSL protocol is given.Based on ACME, the typical implementation of Form Digital Signature Software Framework is put forward.On the basis of component diagram, some typical source codes of the business component are listed and the template description of the currency interface component is showed.The modeling idea and solution are proved to be effective.
