Abstract


At present two applications are in charge of Internet: Web and Email. Web-Mail integrates both advantages. It can provide convenient Email services with beautiful and friendly Web user interface. By the entering of Internet into people’s daily life the network information security shows more and more important gradually. Therefore how to solve the problem of Web-Mail security naturally becomes a valuable research work.The security of Web-Mail comes down to many aspects which include the security of authentication, the security of Email transport, the selection of Email encryption standards, the management of cipher keys, the security of Web communication, and so on. The article first analyses the security goals and risks of Web-Mail. And through the research of the several international common information security architecture standards the Web-Mail security model is established. On the basis of the security model many present information security technologies in terms of different categories are studied carefully. Eventually the Web-Mail security design is brought forward.The PHP language is used to realize an OpenPGP encryption interface functions library and over ten security program modules. After overcoming several technical difficulties that include the realization of the encryption interface library, the process of secure Email formats, the management of users’ cipher keys, the programming of the Web-Mail security subsystem is completed successfully.Then a series of function tests are taken whose result prove that the system works well and have its own particular technical characteristics. These tests show that the system has reached a practical level.At last some typical secure Web-Mail systems in the world are introduced and the compositive comparisons with them are taken. Some future directions are also presented.
