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. In
the articles we discuss how the scheme can be implemented in conjunction with the predominant
routing protocols in ad hoc networks. The article also provides a detailed security analysis of the
proposed protocols, partly based on the use of formal methods.
