Adaptively Secure Garbled Circuits from One-Way Functions
Adaptively Secure Garbled Circuits One-Way Functions
2016/1/26
A garbling scheme is used to garble a circuit C and an input x in a way that reveals the output
C(x) but hides everything else. In many settings, the circuit can be garbled off-line without strict
e...
Fully Key-Homomorphic Encryption, Arithmetic Circuit ABE, and Compact Garbled Circuits
Attribute Based Encryption ABE Key-Homomorphic Public Key Encryption
2016/1/9
We construct the first (key-policy) attribute-based encryption (ABE) system with short
secret keys: the size of keys in our system depends only on the depth of the policy circuit,
not its size. Our ...
Privacy-Free Garbled Circuits with Applications To Efficient Zero-Knowledge
zero-knowledge garbled circuits
2016/1/8
In the last few years garbled circuits (GC) have been elevated from being merely a component
in Yao’s protocol for secure two-party computation, to a cryptographic primitive in its own right,
follow...
Two Halves Make a Whole: Reducing Data Transfer in Garbled Circuits using Half Gates
Garbled Circuits cryptographic protocols
2016/1/7
The well-known classical constructions of garbled circuits use four ciphertexts per gate, although various methods have been proposed to reduce this cost. The best previously known methods for optimiz...
Combining Secret Sharing and Garbled Circuits for Efficient Private IEEE 754 Floating-Point Computations
secure multi-party computation garbled circuits secret sharing
2016/1/5
Two of the major branches in secure multi-party computation research are secret sharing
and garbled circuits. This work succeeds in combining these to enable seamlessly switching
to the technique mo...
We consider secure two-party computation in a multiple-execution setting, where two parties
wish to securely evaluate the same circuit multiple times. We design efficient garbled-circuitbased
two-pa...
How to Compress (Reusable) Garbled Circuits
Functional Encryption Reusable Garbled Circuits
2014/3/6
A fundamental question about (reusable) circuit garbling schemes is: how small can the garbled circuit be? Our main result is a reusable garbling scheme which produces garbled circuits that are the sa...

Zero-knowledge Garbled Circuits Secure Two-Party Computation Active Security
2013/4/18
Zero-knowledge protocols are one of the fundamental concepts in modern cryptography and have countless applications. However, after more than 30 years from their introduction, there are only very few ...
Garbled Circuits Checking Garbled Circuits: More Efficient and Secure Two-Party Computation
Secure Two-Party Computation Cut-and-choose 2PC
2013/2/21
Applying cut-and-choose techniques to Yao's garbled circuit protocol has been a promising approach for designing efficient Two-Party Computation (2PC) with malicious and covert security, as is evident...
Succinct Functional Encryption and Applications: Reusable Garbled Circuits and Beyond
functional encryption
2013/2/21
Functional encryption is a powerful primitive: given an encryption $\Enc(x)$ of a value $x$ and a secret key $\sk_f$ corresponding to a circuit $f$, it enables efficient computation of $f(x)$ without ...
Garbled Circuits for Leakage-Resilience: Hardware Implementation and Evaluation of One-Time Programs
Garbled Circuit Hardware Implementation Leakage-Resilience One-Time Programs Secure Function Evaluation
2010/7/13
The power of side-channel leakage attacks on cryptographic implementations is evident. Today's practical defenses are typically attack-specific countermeasures against certain classes of side-channel ...
