At CRYPTO 2018, Cramer et al. introduced a secret-sharing based protocol called SPDZ2kZ2k that allows for secure multiparty computation (MPC) in the dishonest majority setting over the ring of integer...
In this work we continue the study on the round complexity of secure multi-party computation with black-box simulation in the simultaneous broadcast model where all the parties get the output.
We study the problem of constructing secure multiparty computation (MPC) protocols in the standard broadcast communication model from {\em minimal} assumptions. We focus on security in the plain model...
Many implementations of secure computation use fixed-key AES (modeled as a random permutation); this results in substantial performance benefits due to existing hardware support for~AES and the abilit...
Multi-key fully homomorphic encryption (MKFHE) allows computations on ciphertexts encrypted by different users (public keys), and the results can be jointly decrypted using the secret keys of all the ...
Fairness in Secure Multiparty Computation (MPC) is known to be impossible to achieve in the presence of a dishonest majority. Previous works have proposed combining MPC protocols with Cryptocurrencies...
Guaranteed output delivery: We also construct protocols that achieve security with guaranteed output delivery: (i) Against fail-stop adversaries, we construct two round MPC either in the (bare) public...
Secure multi-party computation (MPC) is a general cryptographic technique that allows distrusting parties to compute a function of their individual inputs, while only revealing the output of the funct...
Secure multiparty computation (MPC) addresses the challenge of evaluating functions on secret inputs without compromising their privacy. An central question in multiparty communication is to understan...
We study the minimal number of point-to-point messages required for general secure multiparty computation (MPC) in the setting of computational security against semi-honest, static adversaries who may...
Secure multiparty computation allows mutually distrusting parties to compute a function on their private inputs such that nothing but the function output is revealed. Achieving fairness --- that all p...
A crucial issue, that mostly affects the performance of actively secure computation of RAM programs, is the task of reading/writing from/to memory in a private and authenticated manner. Previous works...
We study the problem of non-interactive multiparty computation (NI-MPC) where a group of completely asynchronous parties can evaluate a function over their joint inputs by sending a single message to ...
We present MCMix’, an anonymous messaging system that completely hides communication metadata and can scale in the order of hundreds of thousands of users. Our approach is to isolate two suitable fun...
The present report contains a proof of a linear lower bound for a typical three-party secure computation scheme of nn independent ANDAND functions. The goal is to prove some linear communication lower...
