本文介绍了网络安全基础设施可信保障体系建设的现状、问题及未来构建策略。通过对现有安全保障体系建设现状和存在问题的剖析，提出我国网络安全基础设施亟须构建基于主动防御思想的可信技术保障体系。为此，提出可信技术保障体系建设策略建议，主要包括：以自主创新的主动防御计算体系结构作为构建可信技术保障体系的突破点；在落实信息安全系统国产化的战略合作中一定要真正形成实质的本土化；加大自主创新力度，推动主动防御的理论研究、产品研发和工程应用；积极推进可信计算标准的制定和推广应用工作，以推动可信技术保障体系的规范化发展，开展试点示范。

This paper introduces the status, problems, and future strategies of the cyberspace security infrastructure system, and proposes that cyberspace security infrastructure must be based on active defense. Therefore, this paper proposes several suggestions for a trusted technology insurance system, which include the following: In order to build a trusted technology insurance system, independent innovation in active defense must be the breaking point; key information security systems must be developed by local institutions; independent innovation must be increased; research, product development, and active defense applications must be promoted; the development of trusted computing standards must be promoted; and experimental demonstrations must be carried out.
