With the increasing demand for data sharing and value transmission in the digital era, the development of new generation information technologies are expected to break down system barriers and achieve efficient collaborations among different organizations. Cross-domain synergy has drawn much academic and industry attentions since it can form effective connections among various production factors, organizations, and affairs. However, due to the lack of mutual trust mechanisms, it’s hindered by the consideration of responsibility, risk and interest. In this paper, we study the trustworthy challenges in the shared 5G scenario systematically, i.e., system trustworthy, data trustworthy and behavior trustworthy, and propose a notion of Trustworthy Space. Furthermore, we design three independent trust zones for Trustworthy Space, which can ensure the integrity of multi-party data, autonomous interaction of systems, and verifiability of behavior. A typical application of 5G network co-construction and sharing shows that our proposed trusted infrastructure has achieved significant results.
