We propose a new security class, called plaintext-simulatability, defined over the public-key encryption schemes. The notion of plaintext simulatability (denoted PS) is similar to ...

Anonymous channels or similar techniques that can achieve sender's anonymity play important roles in many applications. However, they will be meaningless if cryptographic prim...

Suppose that you want to delegate the ability to process your data, without giving away access to it. We show that this separation is possible: we describe a "fully homomorph...

We introduce the notion of non-malleable noninteractive zero-knowledge (NIZK) proof systems. We show how to transform any ordinary NIZK proof system into one that has strong non-m...

An authenticated encryption scheme is a symmetric encryption scheme whose goal is to provide both privacy and integrity. We consider two possible notions of authenticity for such ...
