Abstract: Various embodiments enable broadcast communications security. Various embodiments enable the authentication of broadcast communications. Various embodiments may enable asymmetric authentication and integrity protection of small size messages, such as one or more signed messages totaling a length of 250 bytes or less. Various embodiments may support cryptographic signing of beacon type messages using certificates. Various embodiments may include generating a beacon type message, cryptographically signing the beacon type message at least in part using a certificate to generate a signed beacon message, and sending the signed beacon type message in one or more broadcast transmissions in conjunction with, or independently of, certificate information used to verify the signed beacon message.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive a broadcast remote identification (BRID) message from a unmanned aerial vehicle (UAV), where the BRID message may include an identity of the UAV. The wireless device may identify UAV information associated with the UAV based on the UAV ID. In some cases, the wireless device may be configured with information that enables the identification of the UAV information. In other cases, the wireless device may request the UAV information from a network entity, such as a UAV flight management system (UFMS), which provides the requested UAV information. In some examples, the UFMS may request the UAV information from an unmanned aerial system (UAS) service supplier (USS) based on the BRID information. Upon identifying the UAV information, the wireless device may broadcast the UAV information to manned aerial vehicles, thereby indicating a presence of the UAV.

Abstract: In embodiments of systems and methods for managing an unmanned aerial vehicle (UAV) identity, a processor of a network computing device may generate an anonymity token that is associated with a digital certificate of a UAV, provide the anonymity token to the UAV for use in operations, receive a request to authenticate the UAV, wherein the request includes the anonymity token, determine whether the anonymity token included in the request is associated with the digital certificate, and send an indication that the UAV is authenticated responsive to the request in response to determining that the anonymity token included in the request is associated with the digital certificate.

Abstract: Methods and devices and systems for implementing the methods for authenticating plaintext and ciphertext in a vehicle-to-everything (V2X) message include generating ciphertext from a plaintext message to be transmitted in a V2X message, generating a hash of the ciphertext and a hash of the plaintext message, generating a digital signature of a concatenation of the hash of the ciphertext and the hash of the plaintext message, and sending to a network node a V2X message that includes the ciphertext, the hash of the plaintext message, and the digital signature. The hash of the plaintext message, and the digital signature may be configured to enable the network node to verify that the V2X endpoint node signed the concatenation.

Abstract: Methods and devices for implementing the methods for communicating vehicle-to-everything (V2X) information to a network node include transmitting a first V2X message that is associated with a first service and that includes an identifier of a second service, and transmitting a second V2X message that is associated with the second service and that includes an identifier of the first service configured to enable the network node to use information from the first V2X message with the second service. The network node may receive the first V2X message and the second V2X message, and may use information from the first V2X message with the second service.

Abstract: A method of controlling a radio-frequency (RF) transaction region comprises: determining a value of a characteristic associated with an ability of roadside equipment, associated with an RF transaction, to obtain information from a user equipment (UE) in the RF transaction region; determining, based on the value of the characteristic, a value of a parameter affecting the ability of the roadside equipment to obtain the information from the UE in the RF transaction region; and conveying the value of the parameter to the UE to affect transmission of messages from the UE to the roadside equipment.
