Quantum cryptography exploits principles of quantum physics for the secure processing of
information. A prominent example is secure communication, ie, the task of transmitting …

Processing encrypted signals requires special properties of the underlying encryption
scheme. A possible choice is the use of homomorphic encryption. In this paper, we propose …

We present VC3, the first system that allows users to run distributed MapReduce
computations in the cloud while keeping their code and data secret, and ensuring the …

Boosting is a general method for improving the accuracy of learning algorithms. We use
boosting to construct improved privacy-pre serving synopses of an input database. These …

In recent years, lattice-based cryptography has been recognized for its many attractive
properties, such as strong provable security guarantees and apparent resistance to quantum …

We propose a fully functional identity-based encryption scheme (IBE). The scheme has
chosen ciphertext security in the random oracle model assuming an elliptic curve variant of …

Cryptography is concerned with the conceptualization, definition, and construction of
computing systems that address security concerns. The design of cryptographic systems …

Cryptography plays a key role in ensuring the privacy and integrity of data and the security of
computer networks. Introduction to Modern Cryptography provides a rigorous yet accessible …

Background Elliptic curve cryptographic schemes were proposed independently in 1985 by
Neal Koblitz (Koblitz 1987) and Victor Miller (Miller 1986). They are the elliptic curve …

We propose a novel paradigm for defining security of cryptographic protocols, called
universally composable security. The salient property of universally composable definitions …
