Disclosed is an operation method of an application server in a wireless communication system, the operation method comprising the steps in which the application server: receives, from a terminal, an application session establishment request including identification information about a first key, wherein the terminal generates the first key and the identification information about the first key on the basis of a network and a primary authentication, an authentication server function (AUSF) generates the same first key and identification information about the first key on the basis of the primary authentication, and the application server determines a first application security key on the basis of the identification information about the first key; transmits an application session establishment response message to the terminal on the basis of the first application security key; and receives data from the terminal through the established application session. L'invention concerne un procédé de fonctionnement d'un serveur d'applications dans un système de communication sans fil, le procédé de fonctionnement comprenant les étapes lors desquelles le serveur d'applications: reçoit, en provenance d'un terminal, une demande d'établissement de session d'application comprenant une information d'identification concernant une première clé, le terminal générant la première clé et l'information d'identification concernant la première clé sur la base d'un réseau et d'une authentification primaire, une fonction de serveur d'authentification (AUSF) génèrant la même première clé et l'information d'identification concernant la première clé sur la base de l'authentification primaire, et le serveur d'applications détermine une première clé de sécurité d'application sur la base de l'information d'identification concernant la première clé; transmet un message de réponse d'établissement de session d'application au terminal sur la base de la première clé de sécurité d'application; et reçoit des données en provenance du terminal par l'intermédiaire de la session d'application établie. 본 개시는 무선 통신 시스템에서 어플리케이션 서버의 동작 방법에 있어서, 어플리케이션 서버가 단말로부터 제1 키의 식별 정보를 포함하는 어플리케이션 세션 설립 요청을 수신하는 단계로서, 단말은 네트워크와 1차 인증(primary authentication)에 기초하여 제1 키 및 제1 키의 식별 정보를 생성하고, AUSF (authentication server function)는 1차 인증에 기초하여 동일한 제1 키 및 제1 키의 식별 정보를 생성하고, 어플리케이션 서버가 제1 키의 식별 정보에 기초하여 제1 응용 보안키를 결정하는 단계, 제1 응용 보안키에 기초하여 단말로 어플리케이션 세션 설립 응답 메시지를 전송하는 단계, 및 단말로부터 설립된 어플리케이션 세션을 통해 데이터를 수신하는 단계를 포함할 수 있다.
