Various types of certificates are basic tools of moderncryptography and networks security. They are used invarious protocols, in the form of public key identitycertificates, binding a key to its owner or in the form ofattribute certificates, being a proof of rights andcapabilities of their owner. Management of certificates(creation, distribution, verification, and revocation) isdependent on a certification infrastructure comprisingvarious certification authorities, protocols, and policies.In this paper we consider usage and management ofcertificates in open, ad hoc networks. Ad hoc networksdiffer from fixed, wired networks in several importantaspects, one of them being that access to the Internet isnot always available. This significantly influencescertificate management protocols since online access tovarious certificate system resources (CA certificates,CRL, etc) is not always available. In this paper wespecify security requirements and constraints in suchenvironments and outline some potential solutions foradaptation of certificate management protocols to thesenew network environments.
