Abstract


With the electronic and information technology and the rapid development of digital networks, widely used in office automation, e-government, e-commerce and more in the field of office. Electronic documents instead of traditional written documents, instead of manual transmission network has become the most important electronic document transmission medium. The official carrier and the transmission of electronic media to promote the development of office automation, greatly improving efficiency, saving manpower and material resources. But at the same time, electronic documents used in the network environment, in particular in the electronic document, in use is also facing some problems. Electronic documents are kept in storage devices, the network can transmit data using the software on a host of other related documents be revised data, it is an easy task and can not be observed by virtue of amendments to the scene. The network is a virtual world, no one could know for sure that one end of the communication network’s identity, real or fake? In practice, this means that the network environment in the electronic document security, integrity and identity of the operator and operation of the act of non-repudiation, has not been very good protection.In this paper, the electronic signature system design and development, is against the above-mentioned problems. Electronic Signature is the specific electronic signature, digital signature of the formal. The trend in information technology, electronic signatures, electronic information is to protect the security, integrity, authentication and non-repudiation of the solution, and its legal effect equivalent to the manual signature, in order to China’s national conditions, with the extension of official forms, The need for electronic signatures in order to seal image forms, that is, the electronic signature.First of all articles on the theory of passwords were studied. For the protection of the integrity of documents and non-repudiation, public key cryptography algorithms have a lot of advantages. This article was followed on the PKI system are discussed. PKI is the electronic signature-based security system is to provide security services facilities. In order to better protect the certification and so on, we are introducing digital certificates, the use of CA and its strict management. Electronic signature systems also need to set out a one-way function and digital signature technology, to protect the integrity of documents and non-repudiation, so for them this article discussed in detail. Finally, in theoretical studies based on electronic signature systems analysis, system design, and electronic signature systems. E-signature systems have been tested to meet the design requirements to meet the needs of the project.
