According to the practical application requirements of coal mine safety monitoring system,proposed the idea of without reconstruction of XML documents to achieve its dynamic XML data encryption based on encryption policy.In this dynamic encryption process,encryption data is divided by user in accordance with different staff for different data access request.This paper detailed analyzes data flow structure of the user requests,encryption policy,and dynamic encryption algorithm of requested XML documents based on user roles.Practice shows it is convenient,flexible,easy expand,and have some practical value to achieve a dynamic user data encryption by XML formatted and the encryption policy set.
