Authentication in Outsourced Database Systems

Speaker: George Kollios

Abstract

In this talk I will discuss authentication problems in outsourced database (ODB) systems. In such systems, the database owner publishes its data through a number of remote servers, with the goal of enabling clients at the edge of the network to access and query the data more efficiently. As servers might be untrusted or can be compromised, query authentication becomes an essential component of ODB systems. In this talk I am going to present solutions to this problem assuming a dynamic setting, where the data owner updates the database periodically.
