E-government , e - documents is an important content . Given on the basis of analysis of various documents program goals and needs of electronic documents in standard secure XML - based electronic documents in standard , the standard is a safe , versatile , open documents standard , scalable , modifications and peer review of the documents can be achieved , countersigned with multiple signatures , approval , multiple granularity of encryption , retrieval and query , registration and other basic operations . Meanwhile, since the encryption and signature algorithm information , the key information , the processing information is complete including among Official XML document . In addition, we also study the problem of computing technology such . The use of peer-to-peer computing model from a new angle , to play its flexible topology architecture , the flexible structure of the entities based on the characteristics of the high-level communication mechanism of XML easy to expand , document workflow and document processing . With a strict hierarchical trust model , entities status depends on its organizational structure , responsibilities and powers , this is a real organization management level computational model of the natural and reasonable . Also studied closely related to the security document system password security , the secret key protection , electronic seal , official documents confidential distribution to improve a one-time password - based authentication protocol , an easy to remember , high security password generator , and a centralized key protection , a distributed key protection program , the basic needs of the electronic seal and gives a feasible solution .
