Description

English:
Certificate type identifier for device and Internet of Things (IoT) certificates, used for device identity authentication, secure access and encrypted communication; the certificate subject is usually bound to the device unique identity.
Status: registered but unused. No device certificate has been issued with this type identifier; when used, map it to the device policy (1.3.6.1.4.1.59719.5.1.230) and bind the subject to the device unique identity (1.3.6.1.4.1.59719.1.100). The unused state shall be re-verified at each revision of this file.
Recommendation: plan for massive scale from the start: automatic enrolment, automatic renewal, bulk revocation and a lightweight revocation checking method for constrained devices.
See also: 1.3.6.1.4.1.59719.5.1.230, 1.3.6.1.4.1.59719.5.3.1, 1.3.6.1.4.1.59719.2.700.
Verification: 2026-10-22 — this arc and all its sub-ordinates are confirmed unused; re-verify the unused state at each revision of this file.

中文:
设备与物联网（Internet of Things，IoT）证书的证书类型标识，用于设备身份鉴别、安全接入与加密通信，证书主体通常与设备唯一身份绑定。
状态：已注册但未使用。尚未以本类型标识签发任何设备证书；使用时应映射到设备策略（1.3.6.1.4.1.59719.5.1.230），并将主体与设备唯一身份（1.3.6.1.4.1.59719.1.100）绑定。本文件每次修订时须重新核验该未使用状态。
建议：从一开始就按海量规模规划——自动注册、自动续期、批量吊销，以及面向资源受限设备的轻量吊销校验方式。

核验：2026-10-22 —— 本弧及其全部下级标识均确认未使用，本文件每次修订时须重新核验该未使用状态。
