[기획-디지털 ID 표준] ⑮산업단체와 포럼 - 오픈ID(OpenID)
2023-10-30 오후 2:46:13
▲ 디지털 ID 산업의 발전 전략 [출처=iNIS]
디지털 ID(Digital Identity) 분야에서 상호운용(interoperable)이 가능하고 안전한 서비스 보장을 위한 표준에 대한 수요가 증가하고 있다. 다양한 표준 조직 및 산업 기관이 활동하는 이유다.
디지털 ID 표준을 개발하는 곳은 유럽표준화기구(European Standardisation Organistions), 국제표준화기구(International Standardisation Organisations), 상업 포럼 및 컨소시엄, 국가기관 등 다양하다.
산업단체와 포럼은 공식적으로 표준화 조직으로 간주되지 않지만 디지털 ID 영역을 포함한 특정 영역에서는 사실상의 표준을 제공하고 있다.
몇몇의 경우 이들 단체들이 추가 비준을 위해 자신들이 생산한 사양을 ISO/IEC, ITU 통신 표준화 부문(ITU-T), ETSI 등 표준 기관에 제출할 수 있다.
이러한 산업단체 및 포럼에는 △인증기관브라우저 포럼(Certification Authority Browser Forum, CA/Browser Forum) △클라우드 서명 컨소시엄(Cloud Signature Consortium, CSC) △국제자금세탁방지기구(Financial Action Task Force, FATF) △신속온라인인증(Fast Identity Online, FIDO) △국제인터넷표준화기구(Internet Engineering Task Force, IETF) △구조화 정보 표준 개발기구(오아시스)(Organization for the Advancement of Structured Information Standards, OASIS) △오픈ID(OpenID) △SOG-IS(Senior Officials Group-Information Systems Security) △W3C(World Wide Web Consortium) 등이다.
오픈ID(OpenID)는 개인 및 기업의 비영리 국제 표준화 조직으로 OpenID(개방형 표준 및 분산 인증 프로토콜)를 활성화, 홍보, 보호하기 위해 노력하고 있다.
오픈ID 코넥트 코어(OpenID Connect Core)는 핵심 OpenID 기능을 정의하고 있다. OpenID 기능은 OAuth 2.0 기반에 구축된 인증과 최종 사용자에 대한 정보를 전달하기 위한 클레임의 사용이다.
추가적인 기술 사양 문서는 검증 가능한 자격 증명 및 검증 가능한 프리젠테이션의 발급을 확장하기 위해 작성됐다. 또한 OpenID Connect 사용에 대한 보안 및 개인 정보 보호 고려 사항에 대해 설명하고 있다.
아래는 오픈ID가 발행한 'OpenID Connect Core 1.0 incorporating errata set 1' 목차 내용이다.
