Analysis and Countermeasures of Data Sharing in the Network Environment

This paper puts forward the framework of sharing data model based on the secure multiparty computation, carries on the design according to the hierarchical structure to progressive realize. The model consists of three layers, the lower is the data access, which manage the data from the node in each domain. The middle layer is a function main body layer, providing various atomic operation based on multi-party secure computation. The top layer is the user interface layer, provides a unified interface for the application, which is convenient extension for cross domain communication.
