Access Control for Energy-Efficient Query Processing

Dongchan An and Seog Park
Abstract—An access control method has been previously performed only focused on safety, and thus not much effort has been done to consider access control in terms of energy efficiency. In this paper, we proposed a method for an energy-efficient query processing of XML data streams, such as a personal digital assistant and a portable terminal, at the client side with limited resources. Specifically, we proposed an access control processing that possesses a small overhead for attaining a secure result in a limited memory and a method to enhance the performance, finding the parts capable of optimizing each processing step for offsetting the overhead caused by the addition of access control processing. Our new method is analyzed through an experiments.
