....This paper improves on previous efforts to secure group authorization (including membership) We do so by employing crypto based identifiers [23] for node and group identification, and then use these in authorization certificates. These allow groups (or nodes) to authorize nodes (or other groups) [10]. Our approach enables highly flexible and robust impromptu security services in an inherently distributed fashion. Previous work on securing impromptu networks has assumed the existence of a traditional PKI, of some web of trust or of some mechanism to distribute keys and shared secrets. We ....

....from impersonation attacks [9] Similar work is underway for the JXTA open source peer to peer protocol. Dynamic and Secure Group Membership: Subsequently, CBID s are used to express authorization via authorization certificates, similar to how they are used to Secure Group Management for IPv6 [10]. Authorization certificates have the following form: Cert = group, node, delegation, tag , validity) In the above, group is a group CBID for the entire impromptu network, or for a subset of it. Appropriately, the certificate is signed with the private key that corresponds to it. Here, node is ....
