去中心化环境中零信任支持的物联网（IoT）平台访问控制服务的功能要求和架构

对去中心化环境中的物联网（IoT）平台，当IoT实体（如IoT设备、IoT服务、IoT网关）相互交互时，在其间建立信任方面存在诸多重大挑战。IoT平台的传统访问控制解决方案（如周边控制、密码认证、虚拟专用网）无法完全应对这些挑战，尤其是当IoT实体部署在去中心化环境中时。
零信任（ZT）是一种网络安全原则，它提供了一系列概念和想法，旨在当面对被视为遭到破坏的网络时，在信息系统和服务中，依据请求访问决策执行准确和最低的权限时，最大限度地降低不确定性[b-NIST SP 800-207]。在基于ZT的访问控制解决方案中，IoT实体不再需要通过位置和安全域来确定访问权限，以发现和访问相同或不同IoT平台中的其他IoT实体。对于任何发现和访问IoT平台中任何IoT实体的请求，都需要确定这一点。因此，基于ZT的访问控制解决方案适用于去中心化环境中的IoT平台。
ITU-T Y.4814建议书介绍了ZT支持的去中心化环境中IoT平台的访问控制服务，并规定了其技术特性、功能要求和架构。
