networked systems to explain to their operators why they are in a certain state--eg, why a …

The number of successful attacks on the Internet shows that it is very difficult to guarantee
the security of online search engines. A breached server that is not detected in time may …

We address the problem of providing users with the ability to assess the integrity of join
