Commodity-Based 2PC for Arithmetic Circuits
Secure Two-Party Computation Information Theoretic Security Oblivious Linear Evaluation
2019/6/19
We revisit the framework of Commodity-based Cryptography presented by Beaver (STOC'97) with a focus on updating the framework to fit with modern multiparty computation (MPC) protocols. We study the po...
Concretely-Efficient Zero-Knowledge Arguments for Arithmetic Circuits and Their Application to Lattice-Based Cryptography
zero-knowledge lattice cryptography MPC
2019/5/23
In this work we present a new interactive Zero-Knowledge Argument of knowledge for general arithmetic circuits. Our protocol is based on the ``MPC-in-the-head''-paradigm of Ishai et al. (STOC 2009) an...

Zero-Knowledge Arithmetic Circuits Sub-linear proofs
2018/6/5
We propose the first zero-knowledge argument with sub-linear communication complexity for arithmetic circuit satisfiability over a prime pp whose security is based on the hardness of the short integer...

Arithmetic Garbled Circuits Constant Round MPC Multiparty Garbling
2017/12/13
We initiate a study of garbled circuits that contain both Boolean and arithmetic gates in secure multiparty computation. In particular, we incorporate the garbling gadgets for arithmetic circuits rece...
A Framework for Constructing Fast MPC over Arithmetic Circuits with Malicious Adversaries and an Honest-Majority
cryptographic protocols Honest-Majority
2017/9/1
Protocols for secure multiparty computation enable a set of parties to compute a function of their inputs without revealing anything but the output. The security properties of the protocol must be pre...
5Gen-C: Multi-input Functional Encryption and Program Obfuscation for Arithmetic Circuits
obfuscation multi-input functional encryption
2017/9/1
Program obfuscation is a powerful security primitive with many applications. White-box cryptography studies a particular subset of program obfuscation targeting keyed pseudorandom functions (PRFs), a ...
On the Untapped Potential of Encoding Predicates by Arithmetic Circuits and Their Applications
Predicates verifiable random functions predicate encryption schemes
2017/8/29
Predicates are used in cryptography as a fundamental tool to control the disclosure of secrets. However, how to embed a particular predicate into a cryptographic primitive is usually not given much at...

2016/12/8
We present simple, practical, and powerful new techniques for garbled circuits. These techniques
result in significant concrete and asymptotic improvements over the state of the art, for several natu...

Sigma-protocol zero-knowledge argument arithmetic circuit
2016/3/9
We provide a zero-knowledge argument for arithmetic circuit
satisfiability with a communication complexity that grows logarithmically
in the size of the circuit. The round complexity is also logarit...
Practical Homomorphic MACs for Arithmetic Circuits

2016/1/3
Homomorphic message authenticators allow the holder of a (public) evaluation key to
perform computations over previously authenticated data, in such a way that the produced tag σ can
be used to cert...
Generalizing Homomorphic MACs for Arithmetic Circuits
Homomorphic Message Authentication Codes Secure Outsourcing Verifiable Computation
2015/12/31
Homomorphic MACs, introduced by Gennaro and Wichs in
2013, allow anyone to validate computations on authenticated data without
knowledge of the secret key. Moreover, the secret-key owner can verify
