Abstract
(EN)
One aspect of the present specification relates to a method for authentication by a user equipment (UE) using biometric information in a wireless communication system, the method comprising the steps of: receiving a challenge code for registration from a network authentication server; displaying a first biometric information input screen for receiving first biometric information, wherein the first biometric information includes information of a user's fingerprint, face, voice, or iris; generating a second public key and a second private key on the basis of the first biometric information received through the first biometric information input screen; displaying a challenge code input screen for receiving a challenge code for confirmation; encrypting the challenge code for confirmation received through the challenge code input screen, and the second public key with a first public key, wherein the first public key is generated in the network authentication server; transmitting the encrypted challenge code for confirmation and the second public key to the network authentication server; and receiving a biometric information authentication registration result message indicating that the second public key is stored in the network authentication server.

Un aspect de la présente invention concerne un procédé d'authentification par un équipement utilisateur (UE) à l'aide d'informations biométriques dans un système de communication sans fil, le procédé comprenant les étapes consistant à : recevoir un code de défi pour l'enregistrement à partir d'un serveur d'authentification de réseau ; afficher un premier écran d'entrée d'informations biométriques pour recevoir des premières informations biométriques, les premières informations biométriques comprenant des informations de l'empreinte digitale, du visage, de la voix, ou de l'iris d'un utilisateur ; générer une seconde clé publique et une deuxième clé privée sur la base des premières informations biométriques reçues par l'intermédiaire du premier écran d'entrée d'informations biométriques ; afficher un écran d'entrée de code de défi pour recevoir un code de défi pour la confirmation ; chiffrer le code de défi pour la confirmation reçue par l'intermédiaire de l'écran d'entrée de code de défi, et la seconde clé publique avec une première clé publique, la première clé publique étant générée dans le serveur d'authentification de réseau ; transmettre le code de défi chiffré pour la confirmation et la seconde clé publique au serveur d'authentification de réseau ; et recevoir un message de résultat d'enregistrement d'authentification d'informations biométriques indiquant que la seconde clé publique est stockée dans le serveur d'authentification de réseau.
