The article proposes a simple, scalable and robust scheme for the distribution of revocation information in mobile ad hoc networks (MANETs). The scheme is intended for ad hoc networks with a planned origin, and where a common point of trust exists. Mobile ad hoc networks have limited available bandwidth. The revocation lists must therefore be specific to the network. They are established with the aid of trusted gateways reporting the identity of the nodes to a central trusted entity. To minimize overhead, the revocation lists are distributed along with the routing messages.
