Title:
ネットワークステアリング情報のセキュア化
Document Type and Number:
Japanese Patent JP7028964
Kind Code:
B2
Abstract:
According to certain embodiments, a method by a user equipment (UE) for securing network steering information includes transmitting a registration request to a Visited Public Land Mobile Network (VPLMN). Upon successful authentication b an authentication server function (AUSF), a home network root key is generated. A protected message comprising Network Steering information is received from a first network node. The protected message is protected using a configuration key (Kconf) and a first Message Authentication Code (MAC-1). The configuration key (Kconf) is determined from the home network root key, and the UE verifies the MAC-1. Based on the Kconf and the MAC-1, it is verified that the VPLMN did not alter Network Steering Information. An acknowledgement message, which is protected with a second Message Authentication Code (MAC-2), is transmitted to a Home Public Land Mobile Network (HPLMN).
