Distributed Data Authentication

Roberto Tamassia, Brown University

Security is an essential requirement of distributed platforms for business applications. We address the problem of authenticating high volumes of data and transactions in non-trusted distributed environments. We present a distributed authentication framework where a data set maintained by a trusted source is replicated at several non-trusted responders, which provide authenticated answers to queries on the data set posed by user. We also discuss applications of this framework to Web services, wireless roaming, and end-to-end integrity of electronic documents.
