New answers tagged multiparty-computation
As I mentioned in a comment, a relatively new application of multi-party computation is its use as a countermeasure against (mainly hardware) side-channel attacks. In particular, there is a method called "threshold implementations" which is based on a form of secret sharing. A relevant reference would be the paper Secure Hardware Implementations of ...
Yes, preprocessing Beaver triples in an offline phase leads to a faster online phase. The online phase of an AND gate requires just two openings plus local computations. But there are other advantages as well. Define a "linear representation" $[x]$ to be any way of representing/distributing a value $x$ among parties such that the following properties hold: ...
Sure. Parties: more than 1 Input: each party has a secret input Output: empty string "Protocol": Each party broadcasts their secret input then outputs the empty string. That is robust for arbitrary thresholds, but is not private against even a single semi-honest adversary.
