M.-H. Guo, Der‐Jiunn Deng · IET Communications · 2011
In the sensor network, the system behaviours are usually presented according to the data monitored, but there are many malicious users who might attack the data. In order to make the sensor network applications work smoothly, it is important to provide the data transmission in highly secure. In this study, we will propose a secure, flexible and integrated conference key mechanism for the sensor networks. The proposal is developed by the elliptic curve cryptography and Lagrange interpolation. Compared to the other researches, the proposal provides lower computing cost, and improves some security problems. The security analysis shows that the proposed mechanism is able to defeat the security attacks, and provide the secure communication for the sensor network.
