Abstract: front page image
(EN)A method for security of a user equipment (UE) identifier used when a network connection is established in a wireless communication system according to an embodiment of the present invention may comprise the steps of: transmitting, to a mobile network operator (MNO), a request for a temporary key used to encrypt the identifier and a ticket for authenticating the authority to access the identifier; receiving the temporary key and the ticket from the MNO; verifying the validity of the ticket; transmitting the ticket to a pseudonym certification authority (PCA) when the ticket is valid; receiving, from the PCA, a subpool which corresponds to the ticket and is encrypted using the temporary key, wherein the encrypted subpool includes a pair of the identifier and the encryption key; and acquiring the identifier by decrypting the encrypted identifier subpool using the temporary key.
(FR)Un mode de réalisation de la présente invention concerne un procédé de sécurisation d'un identificateur d'équipement d'utilisateur (UE) utilisé lorsqu'une connexion réseau est établie dans un système de communication sans fil. Le procédé peut comprendre les étapes consistant à : transmettre, à un opérateur de réseau mobile (MNO), une requête pour une clé temporaire utilisée pour crypter l'identifiant et un ticket pour authentifier l'autorité pour accéder à l'identifiant; recevoir la clé temporaire et le ticket provenant du MNO; vérifier la validité du ticket; transmettre le ticket à une autorité de certification de pseudonyme (PCA) lorsque le ticket est valide; à recevoir, du PCA, un sous-ensemble qui correspond au ticket et qui est crypté à l'aide de la clé temporaire, le sous-ensemble chiffré comprenant une paire de l'identifiant et de la clé de chiffrement; et l'acquisition de l'identifiant en déchiffrant le sous-ensemble d'identifiant chiffré à l'aide de la clé temporaire.
(KO)본 발명의 일 실시예에 따른 무선 통신 시스템에서 네트워크 접속 시 사용되는 UE(User Equipment)의 식별자의 보안 방법에 있어서, 상기 식별자를 암호화하는 데 사용되는 임시 키 및 상기 식별자로의 접근 권한을 인증하는 티켓을 MNO(Mobile Network Operator)에 요청하는 단계; 상기 MNO로부터 상기 임시 키 및 티켓을 수신하는 단계; 상기 티켓의 유효성을 확인하는 단계; 상기 티켓이 유효한 경우, 상기 티켓을 PCA(Pseudonym Certification Authority)로 전송하는 단계; 상기 PCA로부터 상기 티켓과 대응되며, 상기 임시 키로 암호화(encrypt)된 서브풀을 수신하되, 상기 암호화된 서브풀은 상기 식별자 및 암호 키의 페어를 포함함; 및 상기 임시 키를 이용하여 상기 암호화된 식별자 서브 풀을 복호(decrypt)함으로써 상기 식별자를 획득하는 단계; 를 포함할 수 있다.
