(English Abstract)
As demands intending to treat an access control on a client side that was conventionally controlled at a server are surged, it needs a way to treat query processing in effective and secure manners in an environment that has limited resources. Because the access control having been previously performed was only focused on safety, there was little effort to consider the access control in terms of efficiency. Researches about security including access control are started as the security issues are cropped up in a recent stream environment. This paper proposes a method for efficient and secure query processing of XML data streams like a PDA and a portable terminal at the client that is in limited resources. Specifically, this study suggests (1) an access control processing that possesses small overhead for attaining a secure result in a limited memory and (2) a way to enhance the performance, finding the parts being capable of optimizing in each processing step for offsetting the overhead caused by an addition of the access control processing. Superiority of the new method was analyzed by experiment.
