Abstract
Imagine the future: hundreds of embedded computers per person, all
cooperating via ad hoc wireless networks. What will the security
implications be? Peer-to-peer and ubiquitous computing systems involve
many principals, but their network connectivity is intermittent and not
guaranteed. Traditional approaches to authentication, from Kerberos to
public-key certificates, are therefore unworkable, because they rely on
online connectivity to an authentication or revocation server. The paper
considers new solutions. It discusses the Resurrecting Duckling security
policy model. The traditional taxonomy of security threats identifies
three main classes which are considered: confidentiality, integrity or
availability
