Title (EN) SECURITY ESTABLISHMENT METHOD, TERMINAL DEVICE, AND NETWORK DEVICE
(FR) PROCÉDÉ D'ÉTABLISSEMENT DE SÉCURITÉ, DISPOSITIF TERMINAL ET DISPOSITIF DE RÉSEAU

Abstract:
(EN) A security establishment method including: steps (S50, S100) for generating a key pair through mutual authentication between a terminal device (110) and a serving network, the terminal device (110) and the serving network sharing KASME using the generated key pair; a step (S140) in which the terminal device (110) generates KSEAF using KASME, and a SUPI for identifying a subscriber in the serving network; and a step (S150) in which a roaming-destination network of the terminal device (110) generates KSEAF using the SUPI and the KASME issued from the serving network.
(FR) Un procédé d'établissement de sécurité comprend : des étapes (S50, S100) pour générer une paire de clés par l'intermédiaire d'une authentification mutuelle entre un dispositif terminal (110) et un réseau de desserte, le dispositif terminal (110) et le réseau de desserte partageant KASME à l'aide de la paire de clés générée; une étape (S140) dans laquelle le dispositif terminal (110) génère KSEAF à l'aide de KASME, et un SUPI pour identifier un abonné dans le Réseau de desserte; et une étape (S150) dans lequel un réseau de destination d'itinérance du dispositif de terminal (110) génère KSEAF à l'aide du SUPI et du KASME émis à partir du réseau de desserte.
(JA) セキュリティ確立方法は、端末装置(110)とサービングネットワークとの相互認証を通じて鍵ペアを生成し、生成した鍵ペアを用いて、端末装置(110)とサービングネットワークとがKASMEを共有するステップ(S50, S100)と、端末装置(110)が、KASMEと、サービングネットワークにおいて加入者を識別するSUPIとを用いてKSEAFを生成するステップ(S140)と、端末装置(110)のローミング先ネットワークが、サービングネットワークから通知されたKASMEと、SUPIとを用いてKSEAFを生成するステップ(S150)とを含む。
