A method of operating a Master gNodeB (MgNB) in a radio access network RAN is disclosed. An indication of a user plane security policy is received from a core network node, wherein the user plane security policy requires user plane integrity protection for a protocol data unit PDU session. Responsive to the user plane security policy requiring user plane integrity protection for the PDU session and responsive to determining that a secondary base station supporting the user plane security policy requiring user plane integrity protection is unavailable, a data radio bearer DRB of the PDU session is established directly between the MgNB and a user equipment UE. Related MgNBs are also discussed.

In accordance with some embodiments, an apparatus for privacy protection is provided. The apparatus includes a housing arranged to hold a personal communication device and a peripheral interface supported by the housing, where the peripheral interface is connectable to a supplemental functional device. The apparatus further includes a local communication device coupled to the peripheral interface and supported by the housing, where the local communication device includes a personal communication device interface modem operable to provide a communication channel between the peripheral interface and the personal communication device. The apparatus further includes a controller coupled to the peripheral interface and the local communication device, where the controller is operable to manage the communication channel between the supplemental functional device and the personal communication device.

The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate beyond a 4G communication system such as LTE. A terminal according to an embodiment of the present disclosure performs the operations of: transmitting a registration request message to a network node; receiving an authentication request message containing information on a security related capability from the network node; verifying the security related capability by using the authentication request message; transmitting a first message as a response to the authentication request message; receiving a security mode command message from the network node; and transmitting, to the network node, a security mode completion message as a response to the security mode command message, wherein the information on the security related capability includes information on a capability related to security between the terminal and the network node.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a reception occasion for a short message that includes a system information change notification or a public warning system notification. The UE may initiate a mitigation action related to a radio link with a network based at least in part on non-reception by the UE of the short message in the reception occasion, failure of the short message to pass an integrity check, and/or the like. Numerous other aspects are provided.

Precision digital chronography based on detected changes in state of a processor is described. The changes in state may be detected by another processor and an averaged time interval generated. A signal corresponding to the averaged time interval may be communicated to a distributed database and propagated to remote systems. Devices associated with the remote systems may adjust or set a device clock in accordance with the averaged time interval.

One or more MSRP data packets are received from a first MSRP session and creates a first log entry. One or more MSRP data packets are also received from a second MSRP session and create a second log entry. A correlation between the first and second MSRP sessions based on MDNs can be detected, and mapped correlating information to malicious activity. The mapping includes reconstructing MSRP messages sent from a source and encapsulated in a data field of the packets, including MDNs, and matching to at least one threat from a malicious activity database. In response to the threat matching, to conduct a security action on the first and second MSRP sessions.
