Abstract： With the development of mobile communication technology, the 6th Generation mobile networks(6G) network will ease the pressure on the bearer network through distributed network sinking, and optimize resource allocation through distributed coordination. However, how to ensure distributed trustworthiness and help the multi-party collaborative system is an upcoming security challenge. As a distributed ledger technology, blockchain can be applied to cross-domain authentication and cross-domain resource coordination. Blockchain can ensure the transparency of transactions and the credibility of data, and establish a trust relationship between multiple participants, which become the key technology to solve distributed trust.
Key words : distributed trust,；6G；blockchain,；cross-domain authentication,；network slice

第六代移動通信網(wǎng)絡(6th Generation Mobile Networks，6G)具有“萬物互聯(lián),、全球覆蓋,、泛在智能”等多重需求，這些需求使得6G網(wǎng)絡需要成為異構融合的全連接網(wǎng)絡,。同時,，6G網(wǎng)絡需要部署靈活擴展的分布式架構，隨著新技術的不斷成熟以及設備能力的提高,，6G網(wǎng)絡將不僅承載著5G(5th Generation Mobile Networks)網(wǎng)絡既有的業(yè)務,，還需要面對新興的業(yè)務需求，如全息通信,、擴展現(xiàn)實(Extended Reality,，XR)、虛擬現(xiàn)實(Virtual Reality,，VR)等,。這些新興的業(yè)務以及既有業(yè)務的進一步發(fā)展，對網(wǎng)絡的吞吐量,、時延,、可靠性以及連接密度數(shù)提出了更高的要求。網(wǎng)絡的去中心化——分布式網(wǎng)絡架構有望緩解中心網(wǎng)絡的壓力,，提升業(yè)務體驗,。同時6G網(wǎng)絡將從地面擴展到空天地海融合，空天地海一體的泛在接入需求需要分布式網(wǎng)絡架構的支持,，子網(wǎng)與子網(wǎng)之間,、不同運營體系之間需要具備多方運營協(xié)作治理體系，支持多方資源共享,。網(wǎng)絡架構的分布式,、產(chǎn)業(yè)界參與方的豐富化，使得提供多方,、跨域的分布式可信體系成為6G安全需要考慮的問題,。
