In this paper we present the first public key encryption scheme that is structure preserving, i.e., our encryption scheme uses only algebraic operations. In particular it does not...

This paper describes security protocols that use anonymous channels as primitive, much in the way that key distribution protocols ryption as primitive. This abstraction allows us t...

We consider a new model for online secure computation on encrypted inputs in the presence of malicious adversaries. The inputs are independent of the circuit computed in the sense ...

Imagine many small devices send data to a single receiver, encrypted using the receiver’s public key. Assume an adversary that has the power to adaptively corrupt a subset of the...

Abstract. We present a public-key encryption scheme with the following properties. Given a branching program P and an encryption c of an input x, it is possible to efficiently com...
