Abstract: Multimodal cyberspace identification is a basic work for the construction of multimodal cyberspace. This paper summarizes the current state of identification system research both domestically and internationally, and provides a comparative analysis of various identification technologies. In view of the large number of communication devices in multimodal cyberspace and the high requirements of endogenous security, a multimodal cyberspace identification technology based on object identifiers is proposed, and the coding rules of tree structure are used to identify and manage largescale communication devices in multimodal cyberspace to improve management efficiency.

Key words: multimodal cyberspace, identification, object identifiers, tree structure, largescale

摘要： 多模态网络空间标识是建设多模态网络空间的一项基础性研究工作.总结了国内外标识体系研究情况，对不同标识技术进行了对比.针对多模态网络空间通信设备数量多、内生安全要求高等特点，提出基于对象标识符的多模态网络空间标识技术，利用树状结构的编码规则对多模态网络空间中的大规模通信设备进行标识管理，提高管理效率.
