Abstract
KRB-CCN
– a complete authorization and access control system for private CCN networks. Inspired by Kerberos in IP-based networks, KRB-CCN
involves distinct authentication and authorization authorities. By doing so, KRB-CCN
obviates the need for producers to make consumer authentication and access control decisions. KRB-CCN
preserves consumer privacy since producers are unaware of consumer identities. Producers are also not required to keep any hard state and only need to perform two symmetric key operations to guarantee that sensitive content is confidentially delivered only to authenticated and authorized consumers. Furthermore, KRB-CCN
works transparently on the consumer side. Most importantly, unlike prior designs, KRB-CCN
leaves the network (i.e., CCN routers) out of any authorization, access control or confidentiality issues. We describe KRB-CCN
design and implementation, analyze its security, and report on its performance.
