Abstract:
(EN) The objective of the present invention is to improve situations in which an International Mobile Subscriber Identity (IMSI) is used without authorization. A mobile station UE encrypts an IMSI using a "Public Key", includes the encrypted IMSI in a "NAS Attach Request" and transmits the result to a radio base station eNB. A mobile management device MME receives the "NAS Attach Request" via the radio base station eNB and decrypts the encrypted IMSI contained in the "NAS Attach Request" using a "Private Key" corresponding to the "Public Key".
(FR) La présente invention vise à améliorer des situations dans lesquelles une Identité d'Abonné Mobile Internationale (IMSI) est utilisée sans autorisation. Une station mobile, UE, chiffre une IMSI au moyen d'une "clé publique", incorpore l'IMSI chiffrée à une "demande de rattachement NAS", et transmet le résultat à une station de base radio, eNB. Un dispositif de gestion mobile, MME, reçoit la "demande de rattachement NAS" via la station de base radio, eNB, et déchiffre l'IMSI chiffrée contenue dans la "demande de rattachement NAS" au moyen d'une "clé privée" correspondant à la "clé publique".
(JA) IMSIが不正利用される状況を改善する。移動局UEが、"Public Key"を用いてIMSIを暗号化し、暗号化されたIMSIを"NAS Attach Request"に含めて無線基地局eNBへ送信し、移動管理装置MMEは、無線基地局eNBを介して該"NAS Attach Request"を受信し、該"NAS Attach Request"に含まれる暗号化後のIMSIを"Public Key"に対応する"Private Key"を用いて復号する。
