In a secure mediated information system, confidentiality is one of the main concerns when transmitting data from datasources to clients via a mediator. We present three approache...
Similar to verifiable shuffling (or, mixing), we consider the problem of verifiable rotating (and random re-encrypting) a given list of homomorphic encryptions. The offset by which...

In this paper, we study the question of whether or not it is possible to construct protocols for general secure computation in the setting of malicious adversaries and no honest m...
Server-based collaborative filtering systems have been very successful in e-commerce and in direct recommendation applications. In future, they have many potential applications in...
Many protocols that are based on homomorphic encryption are private only if a client submits inputs from a limited range S. Conditional disclosure of secrets (CDS) helps to overcom...
