SWORDS: Improving Sensor Networks Immunity under Worm Attacks

Since sensor nodes are implemented in embedded computer systems, which do not have complicated hardware architecture and operating system. Therefore, worm attacks, which exploit buffer-overflow vulnerabilities, could compromise the entire sensor network by sending a single mal-packet. To address the severe problem, the technique of software diversity has been leveraged to defend against sensor worms. In this paper, we encompass random sensor node scheduling and software diversity to propose a novel sensor worm defense scheme. Our scheme can effectively improve the sensor network defensive capability. Then some practical considerations for its real application is proposed. Finally, analytical and simulation results confirm the effectiveness of our scheme in sensor worm defense.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000281568800008&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Computer Science, Information SystemsComputer Science, Theory & MethodsCPCI-S(ISTP)
