Abstract: A wireless device (and method of) and a network node (and method of) are described herein for improving security for positioning without ciphering. In one embodiment, the wireless device is configured to: receive, from a network node, a paging request for a positioning event and a subsequent RRLP PDU; and perform, in response, an MTA procedure comprising a plurality of instances. When performing each instance, the wireless device transmits, to the network node, a RLC data block comprising at least a first field indicating a position of the instance in a sequence of the plurality of instances, and a second field indicating whether the instance is a last instance in the sequence of the plurality of instances. The network node upon receiving the RLC data block will be able to confirm whether the MTA procedure has been compromised by a fake wireless device.

Abstract: A method for secure path discovery in a mesh network at a destination device is disclosed. The method includes receiving a path discovery request from an originator device and selecting a path selection in response to the path discovery request. The method also includes transmitting the path selection to the originator device and receiving a random seed from a provisioner device. The method also includes generating an authentication code based on the random seed, transmitting an authentication code message to an originator device and receiving communications from the originator device only if the originator device receives a verification response message from the provisioner device which confirms that the destination device has been verified.

Abstract: Methods, systems, and devices for real time error recovery are described. The method may include a wireless device, such as a secondary wireless device, communicatively linked with another wireless device, such as a primary wireless device, and may include the wireless device identifying a first nonce value that is set based on a first packet counter value associated with a data packet stream between a source wireless device and the other wireless device, identifying a second nonce value that is set based on a second packet counter value associated with the data packet stream, receiving a first packet from the data packet stream, determining a sequence number for the first packet based on receiving the first packet, and decrypting the first packet using the first nonce value or the second nonce value based on the sequence number for the first packet.

Abstract: Disclosed in the present invention are a method and device for controlling the reporting of a security check failure at a terminal and a computer storage medium. When detecting the failure of an integrity protection check on a first data bearer, the terminal sends first indication information to a network device and starts a first timer, the first indication information being used to indicate the detection of the integrity protection check failure. If the terminal receives second indication information sent by the network device before the first timer expires, the terminal stops the first timer, and if the terminal does not receive second indication information sent by the network device before the first timer expires, the terminal resends the first indication information to the network device and restarts the first timer.

Abstract: A method for providing a code update on a memory-constrained device includes: determining, by a verifying entity, a minimum necessary compressed code space (MNCCS) of the code update; dividing, by the verifying entity, the code update into N chunks; encrypting, by the verifying entity, the N chunks, wherein encrypting the N chunks includes outputting at least one intermediate ciphertext block of each encrypted chunk, wherein the at least one intermediate ciphertext block of each encrypted chunk is permuted and permutation reference information is generated by the verifying entity; and sending, by the verifying entity, the encrypted chunks, the at least one intermediate ciphertext block of each encrypted chunk, and the permutation reference information to the memory-constrained device.

Abstract: The present invention discloses a system for real-time transmission of large-capacity of a deep-sea subsurface mooring based on a Beidou satellite. Data transmission is implemented by a mechanism of single module multi-card switching operation and dynamic subcontracting transmission. A receiving module is connected to a fixed card and is responsible for receiving state information on whether the transmission is successful. A subsurface mooring end antenna and a land-based antenna adopt a network analyzer to perform secondary matching on parameters such as frequency offset and impedance of the assembled antenna, and effectively intercept original data. In addition, arithmetic coding and dictionary coding are adopted for data compression. While an acquisition board terminal processes original valid data, the valid data is compressed to a maximum of one third of the original data, which can be extended into a parallel mode of multiple single-mode multi-card modules.
