Ad Hoc network is self-created, self-organized, and self-administered.

Ad Hoc network is a collection of mobile nodes which can be router and forwarder,and its routing protocols are popularly studied these years.

This paper firstly makes a survey of the recent works about key management for Ad Hoc networks.

Considering the differences between Ad Hoc networks and wire networks,a self-organized group key management scheme was given,which combines symmetric cryptograghy and public-key cryptograghy and applies key tree to manage key.
