Abstract: The present specification proposes a method and a device for transmitting or receiving information in a wireless communication system supporting network slicing. Specifically, a method for transmitting a registration request message for a network by a terminal (user equipment (UE)) in a wireless communication system may comprise the steps of: receiving network slice selection assistance information (NSSAI) for the network, wherein the NSSAI includes at least one of first NSSAI set for the network, second NSSAI allowed to the network, and/or third NSSAI set for the terminal; generating a registration request message on the basis of the NSSAI; and transmitting the registration request message to the network, wherein the registration request message is generated on the basis of a third NSSAI value and/or whether the third NSSAI is included in the NSSAI.

Abstract: A method for securing an identifier of a user equipment used when connecting to a network connection in a wireless communication system, according to an embodiment of the present invention, may comprise the steps of: receiving, from the user equipment, a message requesting a first ticket for authenticating a right to access the identifier in a serving network of the user equipment, wherein the message includes information on a second ticket for authenticating a right to access the identifier in a home network of the user equipment; transmitting the information on the second ticket to a mobility management entity (MME) of the home network; receiving, from the MME of the home network, identification information of the user equipment that is determined on the basis of the information on the second ticket; and transmitting, to the terminal, information on the first ticket and a temporary key used to encrypt the identifier in the serving network, on the basis of the identification information.

Abstract: Disclosed is a method for a security configuration in a wireless communication system and an apparatus using the same. Specifically, in a method for performing a security configuration by a UE (User Equipment), the method may comprise steps of transmitting a security capability of the UE to a network, receiving security information determined by the network from the network, and determining an action of the UE, based on a configuration of a security control configured in the UE and the security information received from the network, and the configuration of the security control may includes a security capability item, a control condition of the security capability item, and the action of the UE in accordance with the control condition.
