问题陈述(隐私与合规)
联网汽车就像联网的物联网设备:嵌入式 SIM 卡持续与移动网络互动,使得跟踪车辆、将车辆识别码与 IMEI/IMSI 标识符相关联以及重建驾驶历史在技术上成为可能。与此同时,驾驶员希望隐私得到有力保护,监控受到严格限制,民间社会对 eCall 等救生系统的功能逐渐扩展到广泛的车辆跟踪功能的担忧就凸显了这一点。因此,汽车原始设备制造商面临着双重挑战:他们必须能够支持合法调查和跨境请求,同时最大限度地减少数据暴露、执行目的限制并确保完全透明和可审计性。.
ETSI TS 103 976 in automotive
ETSI TS 103 976 (V1.5.1, November 2025) specifies the interface between an Authorized Organization (AO), such as a law enforcement agency, and a Request Processing System (RPS) operated by an organization that holds vehicle‑related data, typically a vehicle manufacturer or mobility provider. It builds on the ETSI TS 103 120 messaging framework and mandates JSON encoding over HTTPS with TLS 1.3 and mutual X.509 authentication. The specification defines nine question types: VIN‑to‑CommsID and CommsID‑to‑VIN (IMEI, IMSI, MSISDN, MAC address), VIN‑to‑Location and VIN‑to‑Location‑Push, VIN‑to‑UniquePartNumber and UniquePartNumber‑to‑VIN, VIN‑to‑SubscribedServices, VIN‑to‑ConnectedDevices and VIN‑to‑AllocatedUserAccounts. Results can optionally be returned in ISO 20078 containers, and an informative annex addresses access to DSSAD data for automated driving. The interface is deliberately transactional, covering requests and responses rather than live voice or video streams, and must never compromise vehicle safety or security. The preceding study, ETSI TR 103 854, introduced the reference model and use cases that TS 103 976 now turns into a normative, testable interface, with security, audit and assurance requirements set out in its normative Annex A.
