Experiments with Queries over Encrypted Data Using Secret Sharing
To avoid insider attacks one cannot rely on access control to protect a database scheme. Encrypting the database is a better option. This paper describes a working prototype of an ...

Monotone Circuits for Weighted Threshold Functions
Weighted threshold functions with positive weights are a natural generalization of unweighted threshold functions. These functions are clearly monotone. However, the naive way of ...

The role of channel states in secret key generation
In this work, we investigate secret key generation from channel states. We point out, by means of a packet-delaybased attack, that observing its own channel states is not the only ...
