Fog computing composes of neighboring devices, which are connected as cluster to collect and compute data via given algorithms. Compared with cloud computing, it collects and processes data at the edge of device layer, instead of remote data transmission and task scheduling. Fog computing reduces the communication and computation overhead in networking and data aggregating, while preserves data privacy against the cloud center. However, due to the different devices capacities, trust relations, security settings, the concerns are that, if the given data is real and sufficient for analyzing program as input, whether the data processing is done as appointed, and how to prevent secret leakage during the computation. This paper proposes a trustless layer for secure data computing in fog network, where the function accepts “hidden” data as input and generates zero-knowledge computing proof which can be easily verified by public. The combination of secure computing functions and blockchain systems escort trustful business in fog environment.
