Design And Implementation Of PKI / CA Secure Electronic Document Storage System

With the development of information technology,the e-government system is moreand more mature, the application of the increasingly wide. Traditional units anddepartments of security requirements are also actively exploring the security conditionsof informatization construction and information sharing mechanism. So it is a veryimportant subject that how to ensure the Internet stability’s and security’s operationeffectively. And it is also a problem that makes the network administrator headache.Now many kinds of virus are rampant and attack endless. With the administrationloophole and anthropogenic damaged, it is afraid to imagine that what it would be whilethese computers are Hackers penetrated, malicious damaged, obstruction. Hackersstolen bank card ID and password and important personal information that bring panicfor the network users.This paper mainly introduces a solution to confidential electronic documentstorage, exchange, the electronic document security and shared memory system（NetSafety Deposit Box）, file storage security problem background, technical details andapplication effect. Net Safety Deposit Box can provides security, free, convenientinformation access space. This can also reduces the trouble for the user who is carryingthick notebook computers and increases a new preservation of personal data channels.Whether you are in or out, in the office or in the hotel, at home or in the wild, if you canconnect to the internet by using the Internet tools anywhere, you will open the NetSafety Deposit Box through input the ID and password. You can get the information orsave the information.Now Net Safety Deposit Box is only the starting stage in China.QiHu360NetSafety Deposit Box, RuiXing Net Safety Deposit Box,HeZhong Net Safety Deposit Box,Geer Net Safety Deposit Box are the famous in China. This article analysis andunderstands the Net Safety Deposit Box which are at home and abroad function. Thendesigned and developed to achieve Net Safety Deposit Box, independently.The entiresystem adopts C/S design,based on PKI/CA technology, using non symmetricencryption algorithm, realization of the confidential document encryption, encrypted transmission, sharing, exchange and authorized departments work platform featuressuch as roaming.
