Abstract: A method of determining an integrity of an electronic communication device that connects to a 5G core network. The method comprises measuring by an attestation client application executing on the electronic communication device attributes of a universal communication stack (UCS) that executes on the electronic communication device and that promotes communication with the 5G core network; receiving a baseline of UCS attributes comprising norms of UCS attributes and thresholds; comparing measurements of the attributes of the UCS to the baseline by the attestation client application; when the comparisons are within the thresholds, granting communication access by the attestation client application to the 5G core network to a user application that executes on the electronic communication device; and when one of the comparisons exceeds a threshold, denying communication access by the attestation client application to the 5G core network to the user application that executes on the electronic communication device.

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: A network node configured to perform a process that includes receiving a PDU Session Establishment Request message for establishing a PDU session, wherein the PDU Session Establishment Request message was transmitted by a UE and includes a PDU session ID. The process also includes communicating a Session Management (SM) Request comprising the PDU Session Establishment Request to an SMF. The process also includes receiving from the SMF a message that includes: i) the PDU Session ID identifying the PDU session, ii) a PDU Session Establishment Accept message, and iii) a user plane (UP) security policy for the PDU session, wherein the UP security policy for the PDU session indicates: i) whether UP confidentiality protection shall be activated or not for all data radio bearers (DRBs) belonging to the PDU session, and/or ii) whether UP integrity protection shall be activated or not for all data radio bearers (DRBs) belonging to the PDU session.

Abstract: The disclosed computer-implemented method includes applying transport protocol heuristics to selective acknowledgement (SACK) messages received at a network adapter from a network node. The transport protocol heuristics identify threshold values for operational functions that are performed when processing the SACK messages. The method further includes determining, by applying the transport protocol heuristics to the SACK messages received from the network node, that the threshold values for the transport protocol heuristics have been reached. In response to determining that the threshold values have been reached, the method includes identifying the network node as a security threat and taking remedial actions to mitigate the security threat. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: In one embodiment, a method includes receiving, at a tracking server from a user device, a hash value associated with a tracking device. The hash value is computed based on at least a unique identifying value associated with the tracking device. The hash value is configured to expire after a predetermined period of time. The method includes determining that the received hash value is not expired. The method includes identifying the tracking device based on a comparison between a stored hash value and the received hash value. The method includes updating one or more records stored in a database accessible to, and maintained by, the tracking server that are associated with the identified tracking device based on the received hash value.
