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. An adaptively secure scheme allows the adversary to specify the input x ...
Efficient Scalable Constant-Round MPC via Garbled Circuits
Garbled Circuits Constant Round MPC Key-Homomorphic PRFs
2017/9/13
In the setting of secure multiparty computation, a set of mutually distrustful parties carry out a joint computation of their inputs, without revealing anything but the output. Over recent years, ther...
Ridge regression is an algorithm that takes as input a large number of data points and finds the best-fit linear curve through these points. It is a building block for many machine-learning operations...
