Implementing AES via an Actively/Covertly Secure Dishonest-Majority MPC Protocol
[chapter]
2012
Lecture Notes in Computer Science
We describe an implementation of the protocol of Damgård, Pastro, Smart and Zakarias (SPDZ/Speedz) for multi-party computation in the presence of a dishonest majority of active adversaries. We present a number of modifications to the protocol; the first reduces the security to covert security, but produces significant performance enhancements; the second enables us to perform bit-wise operations in characteristic two fields. As a bench mark application we present the evaluation of the AES
