Abstract: Techniques are described to perform network relay security. An example wireless communication method includes receiving, by a network device, a request message that includes an identifier associated with a first communication device; determining, by the network device in response to the receiving, that the first communication device is authenticated based on a local policy of the network device; and sending, by the network device in response to the determining, a message to a second communication device to relay to the first communication device, where the message indicates that the identifier is rejected by the network device for communication with the first communication device, or where the message indicates that the first communication device is triggered to send another identifier.

Abstract: This disclosure generally relates to UE authentication and authorization with an edge data network in communication networks. Such authentication and authorization may be based on the generation and application of an edge computing key for a UE. Such edge computing key may be used for bi-directional authentication and may be dynamically updated during various stages of the authentication and authorization process. The authentication and authorization supports a UE connected to multiple AMFs belonging to different PLMNs.

Abstract: Provided are a subscription data update method and apparatus, a node, and a storage medium, where the method includes: in a case where a first network function node determines that authentication and key management for applications (AKMA) subscription data of a user is updated, determining, by the first network function node, a second network function node storing an AKMA context of the user; sending, by the first network function node, a subscription data management notification message to the second network function node; and receiving, by the first network function node, a subscription data management notification response message sent by the second network function node; where the subscription data management notification response message is sent after the second network function node deletes the AKMA context of the user according to the subscription data management notification message.

Abstract: A soda ash and sodium bicarbonate production method is provided, in which solution mining, pretreatment, stripping, concentration, sodium carbonate decahydrate crystallization, separation, dissolution, sodium carbonate monohydrate crystallization, separation and drying are performed to obtain dense soda ash. A dissolved sodium carbonate decahydrate solution or a concentrated brine 3 is subjected to crystallization, separation and drying to produce sodium bicarbonate.

Causticized sludge generated in causticization is calcined and then recycled for causticization. The process provided herein maximizes the resource utilization.

Abstract: This disclosure generally relates to encrypted communication between terminal devices and service applications via a communication network. Such encrypted communication may be based on various hierarchical levels of encryption keys that are generated and managed by the communication network. Such encrypted communication and key management may be provided by the communication network to the terminal devices as a service that can be subscribed to. The various levels of encryption keys may be managed to improve flexibility of the communication network and to reduce potential security breaches.

Abstract: The present document relates to methods, systems, and devices related to digital communication, and more specifically, to techniques related to AUSF selection in the case of dual registrations in AKMA. One example data communication method includes receiving, by a first network function, a request to retrieve an identifier of a second network function that authenticated a terminal from a third function, the request including a parameter. The method also includes transmitting, by the first network function, a response to the third network function that includes the identifier of the second network function that authenticated the terminal that is identified based on the parameter.

Abstract: In accordance with an embodiment, described herein is a system and method for supporting object-based security features for use with messaging services in an application server environment. Credentials can be associated with a JNDI initial context or a JMS connection instead of a thread. For JNDI operations, a lookup call from the initial context can use a security subject in an initial context regardless of a security subject attached to a current thread of the lookup call. For JMS operations, the object-based security model can be enabled on a JMS connection factory, which is used to create a JMS connection associated a security subject based on credentials supplied to create the JMS connection. The JMS connection performs a plurality of JMS operations on different threads using the security subject. The object-based security model is automatically enabled for JMS connection operations once the JMS is accessed using an OBS-enabled JNDI context.

Abstract: In accordance with an embodiment, a system and method provides a messaging service in a multitenant application server environment. Deployable resources are usable within the multitenant application server environment and groupings of resources are defined by resource group templates within a domain. One or more partitions are provided, with each partition providing an administrative and runtime subdivision of the domain that can be associated with a tenant. Java message service (JMS) resources are defined within a resource group template or a resource group, and instantiated within a partition from the one or more partitions to enable messaging for applications deployed within the partition and between the one or more partition.

Abstract: Provided are systems and methods to generate single-cycle THz pulses from a few tens of nanometers thin layer of split ring resonators (SRRs) via optical rectification of femtosecond laser pulses. The emitted THz radiation, with a spectrum ranging from about 0.1 to 4 THz, arises exclusively from pumping the magnetic-dipole resonance of SRRs around 200 THz. This resonant enhancement, together with pump polarization dependence and power scaling of the THz emission, underpins the nonlinearity from optically induced circulating currents in SRRs, with a huge effective nonlinear susceptibility of 0.8×10?16 m2/V that far exceeds surface nonlinearities of both thin films and bulk organic/inorganic crystals and sheet nonlinearities of non-centrosymmetric materials such as ZnTe.

Abstract: A system and method automatically detect traffic violations on roadways or portions thereof that are restricted for use only by permitted vehicles. The system comprises a controller, a vehicle sensor, and a camera. The vehicle sensor detects vehicle movement on a restricted roadway. Data from the camera and the vehicle sensor are analyzed by the controller to detect a vehicle traveling on the restricted roadway, to gather static vehicle information to determine whether the detected vehicle is permitted to use the restricted roadway, and to determine whether movements of the detected vehicle on the restricted roadway constitute a violation of traffic rules in effect on the roadway. The method captures at least one image of a vehicle on a region of the roadway, detects a vehicle in the region, collects vehicle movement information, and detects a violation of traffic rules in effect using at least the collected vehicle movement information.

Abstract: Multiple-object speed tracking apparatuses are disclosed, including a camera configured to capture a set of images of a monitored area (e.g., a roadway). The camera's longitudinal axis may be positioned at any viewing angle relative to a longitudinal axis of a roadway such that at least two moving objects moving on the roadway are included in a set of high or low resolution images. A computer system is configured to analyze the set of images to detect the two moving objects and substantially simultaneously determine a calculated rate of speed of at least one of the two moving objects. The computer system also provides an on-site speed calibration process for transforming locations of an image among the set of images into real-world coordinates by considering both perspective and scale of the image. An apparatus mount for at least one of either the camera or the computer system is also disclosed.
