Abstract
(EN)
Disclosed is a method and device for performing authentication by using biometric information in a wireless communication system. Specifically, the method for performing authentication by user equipment (UE) by using biometric information in a wireless communication system, according to an aspect of the present invention, may comprise the steps of: receiving a challenge code for registration from a network authentication server; receiving a first public key from the network authentication server; generating a second public key and a second private key on the basis of received first biometric information as an input; encrypting a challenge code for verification and the second public key by using the first public key; transmitting the encrypted challenge code for verification and the encrypted second public key to the network authentication server; and receiving a biometric information authentication registration result message indicating that the second public key has been stored in the network authentication server.

L’invention concerne un procédé et un dispositif pour effectuer une authentification à l'aide d'informations biométriques dans un système de communication sans fil. Spécifiquement, le procédé pour effectuer une authentification par un équipement utilisateur (UE) à l'aide d'informations biométriques dans un système de communication sans fil, selon un aspect de la présente invention, peut comprendre les étapes consistant à : recevoir un code de défi pour l'enregistrement à partir d'un serveur d'authentification de réseau ; recevoir une première clé publique à partir du serveur d'authentification de réseau ; générer une seconde clé publique et une deuxième clé privée sur la base des premières informations biométriques reçues en tant qu'entrée ; chiffrer un code de défi pour la vérification et la seconde clé publique au moyen de la première clé publique ; transmettre le code de défi chiffré pour la vérification et la seconde clé publique chiffrée 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 a été stockée dans le serveur d'authentification de réseau.
