cross-cutting Context Information Management (CIM); NGSI-LD; Enabling chain of trust from Content Sources to Content Consumers Disclaimer
|Publication Date:||1 September 2022|
The present document focuses on the issue of trust and identity, scrutinizing the current landscape, analysing the existing requirements, and pointing out how such current initiatives and requirements can be integrated into the NGSI-LD ecosystem.
The approach revolves around two goals:
• A first goal is decentralization.
• A second goal is not only the verification of the credential, but to have means to distinguish which of its claims can be considered authoritative and which cannot, or, equivalently, to discover information that can be used to evaluate the risk of accepting the claims in the VC.
Thus, the present document examines solutions to verify integrity, and to precisely evaluate attribution and authenticity of NGSI-LD Context Information throughout its lifecycle. The goal is to design technical means for enabling a chain of trust from content sources to content consumers that helps endorse documents, by connecting or embedding verifiable credentials into NGSI-LD documents.
These solutions will then enhance the current NGSI-LD standard (ETSI GS CIM 009) [i.18].
