Abstract: In various embodiments, a vehicle-to-everything (V2X) processing device may receive V2X messages from intelligent transportation system (ITS) stations, analyze information in received V2X messages to detect misbehavior conditions, and add a station identifier associated with a V2X message received from an ITS station to a local blocking list in response to detecting a misbehavior condition in the V2X message received from the ITS station. In some embodiments, the V2X processing device may transmit a misbehavior report to a management entity in response to detecting the misbehavior condition in the V2X message.

Abstract: This disclosure provides methods, devices and systems for improving the security of secure long training field (LTF) transmissions. In some implementations, a transmitting device may perform windowing on a secure LTF, in the frequency domain, so that the resulting time-domain LTF signal is difficult, if not impossible, to predict by any device that observes a portion of the LTF signal. In some aspects, the transmitting device may negotiate the windowing of secure LTFs with a receiving device based on fine timing measurement (FTM) negotiation frames exchanged at the start of an FTM procedure. In some other aspects, the transmitting device may dynamically or adaptively perform windowing on secure LTFs. In such aspects, the transmitting device may indicate whether windowing is performed on a secure LTF based on information carried in a signal field of a physical layer convergence protocol (PLCP) protocol data unit (PPDU) that includes the secure LTF.

Abstract: A method performed by a network node that generates a schedule of communication exchanges between the network node and a small cell of a telecommunications network. The schedule is unique for the small cell among multiple small cells and sets times for sending status signals to the small cell and receiving counterpart response signals from the small cell. When the network node detects non-compliance with the schedule, the network node can begin to monitor the small cell for anomalous activity. Upon detecting that the anomalous activity includes malicious activity, the network node can communicate with the small cell wirelessly to deauthorize the small cell.

Abstract: Techniques for securing control and user plane separation in mobile networks (e.g., service provider networks for mobile subscribers, such as for 4G/5G networks) are disclosed. In some embodiments, a system/process/computer program product for securing control and user plane separation in mobile networks in accordance with some embodiments includes monitoring network traffic on a mobile network at a security platform to identify a Packet Forwarding Control Protocol (PFCP) message associated with a new session, in which the mobile network includes a 4G network or a 5G network; extracting a plurality of parameters from the PFCP message at the security platform; and enforcing a security policy at the security platform on the new session based on one or more of the plurality of parameters to secure control and user plane separation in the mobile network.

Abstract: Techniques for detecting and isolating rogue network entities in a communication network are provided. For example, a method comprises receiving from at least one network entity in a communication network a message identifying one or more network entities suspected of malicious activity operating within the communication network, and initiating one or more remedial actions within the communication network to prevent the one or more network entities suspected of malicious activity operating within the communication network from accessing other network entities in the communication network.

Abstract: Procedures are provided for robust handling of NAS request messages that contain a spurious information element (IE). The spurious information element could comprise a NAS message container containing a NAS message with the wrong procedure type, i.e., a procedure type that does not match the type of the parent NAS message. The spurious information elements could also comprise redundant IEs that are not necessary for the emergency services fallback request.

Abstract: Approaches, techniques, and mechanisms are disclosed for generating subscriptions. According to one embodiment, one or more local features of an input request for service subscription are generated based at least in part on one or more messages originated from a client device that represent the input request. One or more global features of a population of input requests originated from a population of client devices are determined based at least in part on a population of input requests. One or more mapped global features of the input request are generated from the one or more global features via one or more mapping functions. One or more machine learning (ML) based prediction models are applied to the one or more local features and the one or more mapped global features of the input request to compute a fraud score for the input request. The fraud score for the input request is used to determine whether the input request for service subscription is to be accepted.
