Summary:Disclosed is an electronic device comprising: a communication device for transmitting or receiving a signal; a memory; and a processor connected to the communication device and the memory. The memory may store instructions for controlling the communication device so as to cause the processor to: generate a key pair including a public key and a private key; receive authentication information from an authentication server by using the communication device; generate signature data by electronically signing the authentication information on the basis of the private key; generate transaction data including the signature data; transmit the transaction data to a blockchain network; and transmit transaction identification information corresponding to the transaction data to the authentication server. Various other embodiments inferred from the specification are also possible. L'invention concerne un dispositif électronique comprenant : un dispositif de communication destiné à émettre ou à recevoir un signal ; une mémoire ; et un processeur connecté au dispositif de communication et à la mémoire. La mémoire peut stocker des instructions destinées à commander le dispositif de communication de façon à amener le processeur : à générer une paire de clés comprenant une clé publique et une clé privée ; à recevoir des informations d'authentification en provenance d'un serveur d'authentification à l'aide du dispositif de communication ; à générer des données de signature par signature électronique des informations d'authentification sur la base de la clé privée ; à générer des données de transaction comprenant les données de signature ; à transmettre les données de transaction à un réseau de chaînes de blocs ; et à transmettre des informations d'identification de transaction correspondant aux données de transaction au serveur d'authentification. Divers autres modes de réalisation inférés de la présente invention sont également possibles. 신호를 송신 또는 수신하는 통신 장치, 메모리 및 상기 통신 장치 및 메모리와 연결된 프로세서를 포함하는 전자 장치가 개시된다. 메모리는, 프로세서가 공개 키 및 개인 키를 포함하는 키 쌍을 생성하고, 인증 서버로부터 인증 정보를 상기 통신 장치를 이용하여 수신하고, 개인 키를 기반으로 인증 정보에 전자 서명하여 서명 데이터를 생성하고, 서명 데이터를 포함하는 트랜잭션 데이터를 생성하고, 트랜잭션 데이터를 블록체인 네트워크로 전송하고, 트랜잭션 데이터에 대응하는 트랜잭션 식별 정보를 인증 서버로 전송하도록 통신 장치를 제어하게 하는 인스트럭션들을 저장할 수 있다. 이 외에도 명세서를 통해 파악되는 다양한 실시 예가 가능하다.
