The UWB system using the UWB ranging factor definition includes a memory in which a UWB ranging factor definition program is embedded and a processor which executes the program, wherein the program predefines UWB ranging factors to define a scrambled timestamp sequence (STS) index, an encryption key, and a nonce.

A method at a UE may include providing a first NAS connection with a network node through a first access node, wherein a first NAS CID is associated with the first NAS connection. While providing the first NAS connection, a second NAS CID may be allocated for a second NAS connection with the network node through a second access node. A registration request message may be transmitted to the network node to request the second NAS connection, wherein transmitting the registration request message includes performing integrity protection for the registration request message using the second NAS CID. A security mode command message may be received from the network node, wherein the security mode command message corresponds to the registration request message. Responsive to receiving the security mode command message, a security mode complete message may be transmitted to the network node through the second access node.

A computer-implemented method for creating a classified token database usable for dynamically redacting confidential information from communications includes performing natural language processing on training input and determining whether a confidentiality level is present in the training input. The method includes, in response to determining that the confidentiality level is present, adding at least one classified token associated with the training input to a classified token database.

A CAN device is provided with an encryption function and a decryption function. The encryption function allows messages to be encrypted and put onto a CAN bus. The decryption function allows the messages on the CAN bus to be decrypted. The encryption and decryption functions share keys which change over the course of time.

One disclosed example method includes obtaining a meeting cryptographic key; transmitting, from a client device to a video conference provider, a request to initiate an encrypted video conference, the encrypted video conference including a plurality of participants; distributing the meeting cryptographic key to each participant of the plurality of participants; obtaining a public cryptographic key of a key pair, the key pair including the public cryptographic key and a private cryptographic key; encrypting the meeting cryptographic key using the public cryptographic key; transmitting, from the client device to the video conference provider, a request to record the video conference; encrypting audio and video from a microphone and image sensor of the client device using the meeting cryptographic key; transmitting the encrypted audio and video to the video conference provider; and providing the encrypted meeting cryptographic key to the video conference provider.

A first communication device for transmitting data to a second communication device comprises a storage device for storing instructions and a processing circuit coupled to the storage device. The processing circuit is configured to execute the instructions stored in the storage device. The instructions comprise compressing a first packet to a first compressed packet according to a compressor instance, wherein the first packet is associated to a flow identity (ID); generating a first Protocol Data Unit (PDU) comprising the flow ID and the first compressed packet; associating a first sequence number (SN) to the first PDU; encrypting the first PDU to a first encrypted packet; generating a first Packet Data Convergence Protocol (PDCP) PDU comprising the first SN and the first encrypted packet; and transmitting the first PDCP PDU via a first logical channel (LC) to the second communication device.

An improved system and method are disclosed for improving functionality in software applications. In one example, the method includes a computing entity having a network interface, a processor, and a memory configured to store a plurality of instructions. The instructions include instructions for a superblock application having instructions for a function block included therein. The function block is configured to provide functions that are accessible to the superblock application via an application programming interface (API). The functions are provided within the superblock application itself and are accessible within the superblock application without switching context to another application on the computing entity.

The present invention provides methods, apparatuses, and systems for delivering protected streaming content to a receiving device. In an aspect of the present invention, a broadcaster provides streaming content. To ensure viewers are properly authorized, the streaming content is encrypted with a traffic key. The traffic key is provided to the users via a key stream message, which is encrypted with a service key. The user obtains at least one rights object from a rights issuers and the at least one rights object includes the service key so that the streaming content may be used. The at least one rights object also contains information regarding usage rights that may be configured by the rights issuer so that, depending on the user and/or the receiving device, different rights may be available. The key stream message may include a program category variable value that indicates the type of content and in conjunction with the rights object, determines what usage rights exist for the streaming content.

Deep packet inspection of data in a multi-spoke data tunnel inspection architecture is provided. Inspection may include using a data review tunnel module to receive a first portion of a data stream, encrypted with a first encryption scheme, in a first data conduit. The method may also include receiving a second portion of the data stream, encrypted with a second encryption scheme, in the second data conduit. The method may also include decrypting and reconstructing a complete data stream. The complete data stream may be derived from the decrypted and reconstructed first data stream and the decrypted and reconstructed second data stream. The method may then analyze and review the flow of the complete data stream to determine whether the flow of the data stream is associated with a pre-determined likelihood of intrusion, and then prepare a data report based on the analysis and review.

A blockchain network system includes a plurality of sensor devices and a blockchain network. The sensor devices are communicably connected with each other via the blockchain network, and sensor data acquired by the sensor devices is managed on the blockchain network in a distributed manner The sensor device includes a sensor unit for sequentially acquiring sensor data in real space on a frame-by-frame basis, a data processing unit for processing the sensor data, a data storage unit for storing the sensor data, an encryption unit for encrypting the sensor data, and a registration unit for registering the sensor data encrypted by the encryption unit on the BC network. The data processing unit aggregates the sensor data with a predetermined number of frame aggregations. The encryption unit collectively encrypts the sensor data aggregated by the data processing unit with the predetermined number of frame aggregations.
