With the rapid development of computer and information technology, people are focusing on how to find valuable information from the vast contents quickly and efficiently. As a result, the search engine system is a solution to this problem. However, there are few relatively work done in access control for search engine system when security is a critical requirement for broader applications of the technology not only in the current but also in the future. In this paper, an architecture for enterprise security search engine based on role-based access control is presented, and based on this architecture the search engine system can not only crawl the documents from the controlled resource sites but also can return different searching results from the index database according to the user’s different identities and permissions for the same keywords. We believe that the proposed architecture is realistic and secure.
