P4P: Practical Large-Scale Privacy-Preserving Distributed Computation Robust against Malicious Users
14 years 11 months ago
In this paper we introduce a framework for privacypreserving distributed computation that is practical for many real-world applications. The framework is called Peers for Privacy ...
