Efficient, Actively Secure MPC with a Dishonest Majority: a Survey
Emmanuela Orsini
Abstract: The last ten years have seen a tremendous growth in the interest and practicality of
secure multiparty computation (MPC) and its possible applications. Secure MPC is indeed
a very hot research topic and recent advances in the eld have already been translated into
commercial products world-wide. A major pillar in this advance has been in the case of
active security with a dishonest majority, mainly due to the SPDZ-line of work protocols.
This survey gives an overview of these protocols, with a focus of the original SPDZ paper
(CRYPTO 2012) and its subsequent optimizations. It also covers some
alternative approaches based on oblivious transfer, oblivious linear-function evaluation, and
constant-round protocols.
