Abstract: XML （extensive makeup language） keyword search is easy to use， and users do not have to understand the schema， recently is widespreadly concerned by the people. Current researches about the keyword search are mainly focused on the algorithms and the sort of the results， but ignore the security issues. Combining with XML keyword search and XML security control， for the first time， this paper researches the XML keyword search method based on secure access control， including identifying the XML keyword search results based on the secure access control rules， establishing keyword index using security view as well as keyword search algorithm based on the above two aspects， and the three aspects above are on the basis of the XML keyword’s smallest lowest common ancestors （SLCA） and view-based secure access control rules. The experimental result shows that in order to satisfy the secure access control rules， this algorithm although needs extra time to get the correct results but is generally efficient.
