Data Sharing Model Of Network Measurement Based On Secure Multiparty Computation

Now, with network structure becoming more and more complex, collaboration has become an essential part of the network without a trusted third party domain. In research, inter-domain collaboration can help research institutions to improve the range and accuracy of network measurements, to provide high-quality traffic data. In terms of security, cybercrime is very frequent, and the network domain operators only rely on partial information to deal with it. And this is obviously detrimental to the fight against cybercrime. Problems of the collaboration will appear because there are many private information in the inner-domain. We explore how to share data between various closed domain to complete the study.In this paper, we introduced the concept of secure multi-party computation (Secure Multi-Party Computation, SMC) into cross-domain network measurement. And we proposed a network data sharing model based on secure multiparty computation. This model used a layered structure to design. The model is divided into three-tier structure. The bottom layer is the data provider layer, and the core computing layer is in the middle, and the upper layer is the application layer. The data provider layer accepts data entered by the participant which is network measurement data, and the identity of the declaration and registration of the identity of the participants is in this level. The calculated layer is to complete the work of secure multiparty computation protocols and algorithms, and then control these operations to provide interfaces to the upper layer application. The model contains two of important security protocol modules:shamir secret sharing module and security matrix multiplication module. The upper layer is the application layer, and network measurement applications will call secure multiparty computation operation interface to complete the network measurement data sharing.After a detailed description of this model, we introduced two network measurement applications which are developed on the SMC network data sharing model. These applications are the top-k application of routing table and network status detection application. The applications will call shamir secret sharing module and security matrix multiplication module which are two of the most important module, and get measuring results which suggest that the availability of the data sharing model and performance.
