2.1 Introduction

A major concern on studying sharing information in a distributed system containing autonomous entities is how to model adversarial threat. Traditionally, behavior-based model (e.g., semi-honest model) has been widely adopted as the adversary model. In particular, semi-honest adversaries are those that run the protocol exactly as specified (no deviations), but may try to learn as much as possible about the input of the other entities from their views of the protocol. Most traditional solutions have a common assumption that all entities are well disciplined to follow the ...
