  Abstract

Recently, services using distributed identification (DID) technology that guarantee data sovereignty to users, such as the government's mobile driver's license and vaccination certificate service, are gradually appearing. However, the DID ecosystem is at an initial level, and there is no framework to guarantee users' control over their data and interoperability between DID and the existing PKI-based digital signature service. In this regard, we intend to prepare a robust DID ecosystem by proposing a framework basic model that all DID participants, such as issuers, holders, and verifiers, can trust. DID is a new identity verification system that guarantees self-sovereignty to users and can provide data safely and flexibly across fields. In order for users to safely and conveniently use the identity verification service, the government must guarantee the minimum reliability. This can be supplemented with the Trust Anchor model, and there are various methodologies. The trust connection framework basic model proposed in this paper is a policy model that can be the basis for service activation. It aims to contribute to establishing a trust connection system through the basic model and securing interoperability and reliability between DID and PKI services.
