Secure Service and Management for Security-Critical Wireless Sensor Network

For Security-Critical Wireless Sensor Network (SCWSN), security should be given priority in design. In this paper, we analyze the essential security demands for security-critical WSN. Then, we propose our integrated approaches, which are built based on security service and management, to achieve security for security-critical WSN. Finally, we describe how our security solution works against typical attacks. There are four advantage characters to provide against attacks in the SCWSN we designed: feather-weight public key and share key combined key pre-distribution scheme, hop by hop packet signature and encryption in the route path, remote management of nodes and network route, data confidence analysis.
