N2 - The existing group key establishment protocols can not support end-to-end security in the group, and execute the whole re-keying when lost. Moreover, sharing one same key with all members is unfit to ad hoc networks. For overcoming the problems, this paper proposes Diff-key: Different key establishment based on trust-level. The Diff-key, distinguishes all members into two types of trust-level: trust member and un-trust member. Only trust members can establish a group key, and the others make use of a session key through mutual authentication. Therefore, the Diff-key can achieve end-to-end security services and execute partial re-keying when a key is stolen.
