Abstract:
   Named Data Networking (NDN) enables data-centric security in network
   communication by mandating digital signatures on network-layer data
   packets. This change introduces a new issue with data authentication: the
   lifetime of data can be longer than the lifetime of the signatures which is
   limited by the validity periods of the corresponding certificates. In this
   paper, we introduce a new authentication system for archived NDN data, NDN
   DeLorean, which uses a look back validation model that authenticates data
   considering the time point when the data was produced instead of the time it
   is being retrieved. As long as the archived data received a valid signature
   at the time of its production, it can stay valid perpetually. We designed NDN
   DeLorean as a publicly audited timestamp service that maintains a historical
   evidence of the data’s validity. NDN DeLorean creates permanent existence
   proofs of data (and certificates) upon request at a time when the original
   data signatures are valid. With both data and its signing key certificates
   being time stamped, DeLorean frees data producers from necessity to
   periodically re-sign archived data in order to keep it valid.
