Distributed oblivious function evaluation and its applications
This paper is about distributed oblivious function evaluation (DOFE). In this setting one party (Alice) has a function f (x), and the other party (Bob) with an input alpha wants to learn f (alpha) in an oblivious way with the help of a set of servers. What Alice should do is to share her secret function f (x) among the servers. Bob obtains what he should get by interacting with the servers. This paper proposes the model and security requirements for DOFE and analyzes three distributed oblivious polynomial evaluation protocols presented in the paper.
