Recently, the use of XML for data broadcasting in mobile wireless networks has gained many attentions. One of the most essential requirements for such networks is data confidentiality. In order to secure XML data broadcast in mobile wireless network, mobile clients should obey a set of access authorizations specified on the original XML document. In such environments, mobile clients can only access authorized parts of encrypted XML stream based on their access authorizations. Several indexing methods have been proposed in order to have selective access to XML data over the XML stream. However, these indexing methods cannot be used for encrypted XML data. In this paper, we define a new unit structure for XML stream called SecNode which supports data confidentiality of XML data over the wireless broadcast channel. We also define two indexes for the SecNode structure called Min (NCS) and Min (NIS) to efficiently process XML queries over the encrypted XML stream.The experimental results demonstrate using two indexes Min (NCS) and Min (NIS) in the SecNode structure reduces the power consumption of mobile clients in processing XML queries over the encrypted XML stream.
