Method and apparatus for filtering injected bogus data in sensor network, and computer-readable recording medium used thereto

摘要

The present invention relates to a method, an apparatus, and a computer readable recording medium for preventing counterfeit data insertion attacks in a sensor network using independent cell polynomials and cell authenticator vectors for each cell of a sensor field.;A method for preventing forged data insertion attacks in a sensor network according to the present invention comprises generating a cell key in association with a cell polynomial and a cell authenticator vector corresponding to each cell delimiting a sensor field and generating a cell key in the cell. A cell key distribution step of distributing the cell key to a sensor node; Selecting a data aggregation node in which a data aggregation node is selected among the sensor nodes that have discovered the event when a sensor node having received the cell key is found in the cell; A sensor node signature value generation step of generating a sensor node signature value through the distributed cell key, public key, and secret random number at the sensor node that has discovered the event; Generating a final signature value through the sensor node signature value in the data set node to construct a report; And verifying and transmitting the report to the sink node if the report is valid by validating the report using the final signature value and the public key.
