Abstract

With the recent increase in interest in metaverse in which virtual and physical spaces are digitally fused, many activities in physical spaces are expected to take place in web-based virtual spaces. Therefore, there is a need for research on a self-sovereign identity system that can secure privacy and mutual trust in a DID(decentralized identifier)-based virtual space environment. We, in this paper, developed and validated a reliable communication method consisting of DIDComm messages, a procedure for generating distributed identifiers, asymmetric keys, and DID documents based on Hyperledger Indy and DIDComm open sources. The developed communication method can be applied to verify each other by exchanging additional information and verifiable credentials for trust among communication participants.

최근 가상공간과 물리공간이 디지털 융합된 메타버스에 대한 관심이 높아지면서 물리공간에서의 많은 활동이 웹 기반의 가상공간에서 이루어질 전망이다. 따라서 분산 식별자 기반 가상공간 환경에서 사생활과 상호 신뢰를 확보할 수 있는 자기주권 신원시스템에 대한 연구가 요구된다. 본 논문에서는 분산 식별자 기반 자기주권 신원시스템을 위해 Hyperledger Indy와 DIDComm 오픈 소스를 기반으로 분산 식별자, 비대칭 키, DID 문서를 생성하여 블록체인과 지갑에 등록하는 절차, DIDComm 메시지로 구성된 신뢰할 수 있는 통신 방법을 개발하고 검증하였다. 이는 통신 참여자 간의 신뢰를 위한 추가적인 정보 교환 및 검증 가능한 자격증명을 교환하여 서로를 검증하는데 활용이 가능하다
