%X Extensible Markup Language (XML) has become the standard for data interchange on the Internet. In this paper, based on the special structure of XML documents, an access control model (ACM) was brought forth. According to this access control model and different roles of hosts, their characteristics, their relationships and access control base (ACB), an algorithm of grouping and encrypting XML documents was designed. Key-collation table was created and keys were distributed and managed. Hosts use one or more keys to decrypt XML documents and the server is set free. The access of hosts is temporally controlled by ACB. On the basis of access control model, the method of transmitting securely XML documents encrypted according to access control privileges, to hosts of different grades, and the method of security check-up were put forward.
