Method and Management Node Apparatus for Detecting Wormhole Attack in Ubiquitous Sensor Networks

摘要

The present invention relates to a wormhole attack detection method and apparatus of the management node in a ubiquitous sensor network. ; The present invention provides a method for detecting the wormhole attack on the managed node ubiquitous sensor network, (a) the neighboring node connectivity data collection step of the managed nodes collect the neighboring node connectivity data from within the FFD sensor nodes ubiquitous sensor network; (B) incomplete connection matrix generation step by using the management node is the neighboring node, connectivity data for creating an incomplete connection matrix; (C) generating complete connection matrix comprising using the symmetry wherein the management node generates a complete connection matrix from the incomplete connection matrix; (D) a closed loop search method comprising the management node in the closed loop search for the complete connection matrix; (E) repeat experiments confirm message comprising the number of the managed node, and determine the non-overlapping adjacent link can be the non-overlapping adjacent link from said closed loop; (F) to the managed node performs a message repeat experiments the non-redundant number of adjacent links with respect to the non-overlapping adjacent link, the message repeat experiments performed and the delay time measuring step of measuring the delay time for each of said messages repeated experiments; (G) delay time wormhole link extraction step in which said management node extracts the more delay time threshold value of the delay time measured for each experiment repeated the message; And (h) characterized in that an output step outputs the wormhole attack detection which determines the non-overlapping adjacent links of the management node that caused the least delay the extracted threshold value in wormhole links, output wormhole attack detection result which provides a wormhole attack detection method in the ubiquitous sensor network. ; According to the present invention, it is applied to the security field of the ubiquitous sensor network, tapping of the key data, missing, or the inherent properties of the wormhole link wormhole attack by the wormhole link in the change can be generated without having a complicated hardware as detected by a simple software procedure that yeokyiyong, thereby improving security without a significant load to the sensor node in the USN and USN. ; The ubiquitous sensor network, security, a wormhole attack, wormhole link
