Services in MANETs tend to be decentralized in order to share their cost between their subscribers. Security is not an exception and thus shared self-organized security schemes must be provided. Group Key Management (GKM) deals with the responsibility of providing privacy and group authentication in group communications focusing in the dynamism of the group (joins and leaves). We present a shared self-organized GKM protocol targeted to MANETs. Main basis of the presented protocol is to extend GKM protocols based on logical trees of keys towards being non-centralized and self-created.

Keywords: MANET, GKM, group security, distributed, self-organized
