    Abstract: A tracking device can securely communicate with a secondary device by generating a hash value based on the identity of the tracking device. If the secondary device cannot resolve the hash value, the hash value can be provided to a tracking server, such as a cloud server, for resolving the hash value. Upon resolving the hash value, the tracking server can store a location of the tracking device in association with the identity of the tracking device. To preserve power, the secondary device can activate location-detection functionality (such as a GPS receive) only in response to the detection of movement of the tracking device, can obtain location information, and can de-activate the location-detection functionality upon providing the location information to the tracking server. The tracking server can associate one or both of a previous location and the current location information based on movement of the tracking device.

    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).
