Authenticated Group Key Distribution for Unreliable Sensor Networks
Hwaseong Lee, Yon Ho Kim, Dong Hoon Lee · 2008
Chadha et al. proposed a group key scheme for wireless sensor networks via local collaboration. A group key was derived from base station's broadcast message and a node's secret. However, there is no authentication in the group key scheme. It is essential to share a reliable group key among the entire nodes even though it results in a little overhead.
