Design and Implementation of Security System for IPv6 Sensor Networks

This paper analyzes the security requirements for IPv6 Sensor Networks (IPv6 SNs). Aiming at the security threats existed in IPv6 SNs, a security system for IPv6 SNs is designed. In this system, security association, key management, multicast security transmission, attribute-based access control and network security detection are used to ensure the security of IPv6 SNs. The test results show that the system can authenticate the identity of the nodes joining the network, complete the issuance of security materials, and achieve secure multicast. With the security association mechanism, the system also can resist replay attacks and man-in-the-middle attacks, which improves the security of the networks.
