    Abstract: The subject matter described herein includes a method for reducing the likelihood of successful denial of service (DoS) attacks by validating overload control information (OCI) scope information against network function (NF) profile information obtained using target resource identification information. The method includes receiving a service based interface (SB I) request message, obtaining, from the SBI request message, target resource identification information, obtaining NF profile information using the target resource identification information and storing the NF profile information, receiving an SBI response message including overload control information and scope information for the overload control information, using the stored NF profile information to determine whether the scope information for the overload control information is valid, and, in response to determining that the scope information for the overload control information is invalid, rejecting the SBI response message.

    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive, from a base station, control signaling identifying a configuration of a set of time intervals for communication with the base station, the set of time intervals including a subset of the time intervals for which the UE is to perform a physical layer security procedure. In some cases, the UE may activate a timer associated with performing the physical layer security procedure in response to a trigger. The UE and the base station may communicate one or more messages using the physical layer security procedure, for example, in the subset of the time intervals identified by the control signaling, while the timer is active, or both. The physical layer security procedure may involve the UE performing physical layer security encoding, signal jamming, or both.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th Generation (5G) communication system for supporting higher data rates beyond a 4th Generation (4G) system with a technology for Internet of Things (IoT). The method includes comparing plurality of parameters (e.g. TAI) received in message (e.g. initial NAS message, registration request, first protected NAS message) from UE and plurality of parameters (e.g. TAI) broadcasted/received/stored by AMF entity and/or genuine gNB. AMF entity and/or genuine gNB sends an accept message (e.g. NAS accept) or reject message (e.g. NAS reject, RRC reject or RRC reconfiguration.) with appropriate error cause value to UE to mitigate the MitM attack. Based on received message from AMF entity and/or genuine gNB, UE detects that UE is camped on genuine gNB or fake gNB. UE performs action(s) (e.g. cell reselection), when UE is camped on fake gNB/eNB to mitigate MitM attack.

    Abstract: Techniques for preventing rogue network functions in a communication network are provided. For example, a method comprises obtaining information identifying one or more network entities suspected of malicious activity operating within the communication network, causing a re-authorization of the one or more network entities suspected of malicious activity, and in response to a re- authorization failure of at least one of the one or more network entities suspected of malicious activity, causing one or more remedial actions to occur within the communication network to prevent the at least one network entity that failed re-authorization from accessing other network entities in the communication network.
