Zusammenfassung:	The present invention relates to an HD-based computing device DID issuance method. The HD-based computing device DID issuance method comprises the steps of: generating a user DID associated with a user key pair including an HD-based user public key and user private key with a hierarchical structure; storing a DID document corresponding to the generated user DID on a distributed network; receiving a computing device DID issuance request including the phone number and device identifier of a user terminal from an external device; in response to receiving the computing device DID issuance request, generating, based on the user key pair, a computing device DID associated with a computing device key pair including an HD-based computing device public key and computing device private key; and providing the generated computing device DID to the external device. Accordingly, a key associated with a computing device and/or user terminal can be efficiently managed. 본 발명은 HD 기반의 컴퓨팅 장치 DID 발급 방법에 관한 것이다. HD 기반의 컴퓨팅 장치 DID 발급 방법은, 계층 구조를 갖는 HD 기반의 사용자 공개키 및 사용자 개인키를 포함하는 사용자 키 쌍과 연관된 사용자 DID를 생성하는 단계, 생성된 사용자 DID에 대응하는 DID 문서를 분산 네트워크 상에 저장하는 단계, 외부 장치로부터 사용자 단말의 전화번호 및 장치 식별자를 포함하는 컴퓨팅 장치 DID 발급 요청을 수신하는 단계, 컴퓨팅 장치 DID 발급 요청을 수신하는 것에 응답하여, 사용자 키 쌍을 기초로, HD 기반의 컴퓨팅 장치 공개키 및 컴퓨팅 장치 개인키를 포함하는 컴퓨팅 장치 키 쌍과 연관된 컴퓨팅 장치 DID를 생성하는 단계 및 생성된 컴퓨팅 장치 DID를 외부 장치에 제공하는 단계를 포함한다.
