Two-Thirds Honest-Majority MPC for Malicious Adversaries at Almost the Cost of Semi-Honest
secure multiparty computation honest majority concrete efficiency
2019/6/5
Secure multiparty computation (MPC) enables a set of parties to securely carry out a joint computation of their private inputs without revealing anything but the output. Protocols for semi-honest adve...
Fast Distributed RSA Key Generation for Semi-Honest and Malicious Adversaries
cryptographic protocols RSA
2018/6/7
We present two new, highly efficient, protocols for securely generating a distributed RSA key pair in the two-party setting. One protocol is semi-honestly secure and the other maliciously secure. Both...

Improved Private Set Intersection against Malicious Adversaries
cryptographic protocols Private Set Intersection
2016/12/12
Private set intersection (PSI) refers to a special case of secure two-party computation in which the parties each have a set of items and compute the intersection of these sets without revealing any a...
Faster Two-Party Computation Secure Against Malicious Adversaries in the Single-Execution Setting
secure computation garbled circuit cut-and-choose
2016/12/10
We propose a new protocol for two-party computation, secure against malicious adversaries, that is significantly faster than prior work in the single-execution (i.e., non-amortized) setting. In partic...
High-Throughput Secure Three-Party Computation for Malicious Adversaries and an Honest Majority
secure multiparty computation malicious adversaries honest majority
2016/12/8
In this paper, we describe a new protocol for secure three-party computation of any functionality, with an honest majority and a \textit{malicious} adversary. Our protocol has both an information-theo...
Efficient Interval Check in the Presence of Malicious Adversaries
private interval check secure integer comparison malicious model
2016/1/7
We consider the following problem: Assuming that Alice and
Bob have an integer interval [a, e] and an integer b respectively, for a
commitment c to b, Alice and Bob jointly check whether b is within...
On the Oblivious Transfer Capacity of Generalized Erasure Channels against Malicious Adversaries
Oblivious transfer generalized erasure channel oblivious transfer capacity
2016/1/6
Noisy channels are a powerful resource for cryptography as they can be
used to obtain information-theoretically secure key agreement, commitment
and oblivious transfer protocols, among others. Obliv...
More Efficient Oblivious Transfer Extensions with Security for Malicious Adversaries
oblivious transfer extensions concrete efficiency
2016/1/4
Oblivious transfer (OT) is one of the most fundamental primitives in cryptography and is
widely used in protocols for secure two-party and multi-party computation. As secure computation
becomes more...
Blazing Fast 2PC in the Offline/Online Setting with Security for Malicious Adversaries
online consistency check implementation
2015/12/22
Recently, several new techniques were presented to dramatically improve key parts of secure
two-party computation (2PC) protocols that use the cut-and-choose paradigm on garbled circuits
for 2PC wit...
We present a method to compile Yao's two-player garbled circuit protocol into one that is secure against malicious adversaries that relies on witness indistinguishability. Our approach can enjoy lower...
