Research and Implementation of Network and Data Security for Digital Library

This article discusses the security technology in Digital Library system which based on the browser.First it introduces basic security concepts in general, then describes the public key infrastructure. Following that,it discusses how Digital Library supports secure lnternet protocols.The paper adopts identity certification hierarchies, numeric idiograph, certificate authority and security technique of workflow.And it makes the most of using the environment of network, operating system and the security mechanism for Digital Library server.The security mechanism have to be satisfied when accessing and updating the data.
