A method of authenticating a controller by a gateway in a vehicle may include transmitting a first symmetric key to the controller; generating a first one-time authentication value (OTAV), encrypting the first OTAV with the first symmetric key and delivering the encrypted first OTAV to the controller; sending a request for authentication using the first OTAV to the controller; and receiving a hash value from the controller in response to the request.

The present disclosure relates to a method of managing a controller with reliability and, more particularly, to authentication and data exchange during installation/use/removal of a vehicle controller, a gateway and a tester using an encryption algorithm. A method of authenticating a controller by a gateway in a vehicle includes: transmitting a first message including a first random number to the controller when a first condition is satisfied; receiving, from the controller, a second message including the first random number to which an electronic signature has been attached through a private key of the controller; decrypting the first random number having the electronic signature attached thereto using a public key of the controller; and transmitting, to the controller, a symmetric key encrypted using the public key of the controller when the decryption has been successfully performed.

A mobility data storage method executed by a plurality of vehicles each including a sensor and a processor coupled to the sensor, the processor of each of the plurality of vehicles being configured to store a local blockchain, the method includes, with the processor of the plurality of vehicles, attaching a sensor data pool, a random value that excess a threshold, and a verifiable random function (VRF) proof to a respective candidate block then broadcasting the candidate block to all other vehicles. Then, a particular candidate block whose random value is largest among the broadcasted candidate blocks is selected and verified with the VRF proof prior to be attached to the local blockchain.

An example operation includes one or more of receiving, by a transport, a key and a functionality associated with an upcoming event from a server, and performing, by the transport, the functionality when the key is verified and the event begins to occur.

An authentication system and method for an electronic governor of an unmanned aerial vehicle is disclosed. By employing reciprocative authentication and encryption mechanisms between a main control terminal and an electronic governor, the use of a modified electronic governor is prevented and thus the illegal use of UAVs is also prevented. Moreover, the provided electronic governor may be operated in dual-mode to extend its compatibility to conventional main control terminals.

A wireless communication system includes an in-vehicle device mounted on a vehicle; and a portable device that can be carried by a user. The in-vehicle device includes a first sending unit configured to intermittently and wirelessly send an identification code of the vehicle or the in-vehicle device; and a detection unit configured to detect a presence of the portable device by receiving a response signal wirelessly sent from the portable device. The portable device includes a receiving antenna configured to receive the identification code; a first verification unit configured to verify the identification code, received by the receiving antenna, with a code registered in the portable device; and a sending control unit configured to wirelessly send the response signal if the verification by the first verification unit is successful and not to send the response signal if the verification by the first verification unit is not successful.

Systems, methods, and apparatus for inband telemetry for a virtual transponder are disclosed. A disclosed method for inband telemetry for a virtual transponder comprises transmitting, by a payload antenna on a vehicle, a payload signal to a hosted receiving antenna. The method further comprises transmitting, by the payload antenna, a hosted telemetry signal to the hosted receiving antenna. In one or more embodiments, the hosted telemetry signal and the payload signal are transmitted on the same frequency band.

A toll transponder may receive transaction card data identifying a transaction card associated with a transaction account. The toll transponder may provide to a toll server device, and via a toll antenna of a toll collection system, a request for a transaction amount for a vehicle toll, and may receive a response requesting authorization for payment of the transaction amount. The toll transponder may determine, based on the response, an authorization request cryptogram for payment of the transaction amount, and generate an encrypted signal identifying the authorization request cryptogram, the transaction card data, and a toll transponder identifier identifying the toll transponder. The toll transponder may provide the encrypted signal to the toll server device via the toll antenna, and may receive from the toll server device, via the toll antenna, data indicating whether the transaction amount for the vehicle toll is approved.

A computer-implemented method for generating a speeding ticket. The method includes generating a first image of at least a part of a vehicle by a first camera, detecting a first set of the characters of the number plate of the vehicle dependent on the first image, and generating a secured file by a first camera using the first set of the characters and a first character code. The method further includes generating a second image of the part of the vehicle by a second camera and detecting a second set of the characters of the number plate dependent on the second image. The method further includes generating the speeding ticket, in response to determining that the vehicle violates a speed limit and in response to verifying that the first set of the characters is equal to the second set of the characters.

The present disclosure includes apparatuses, methods, and systems for using a local ledger block chain for secure electronic control unit updates. An embodiment includes a memory, and circuitry configured to receive a global block to be added to a local ledger block chain for validating an electronic control unit update for electronic control unit data stored in the memory, where the global block to be added to the local ledger block chain includes a cryptographic hash of a current local block in the local ledger block chain, a cryptographic hash of the electronic control unit data stored in the memory to be updated, where the current local block in the local ledger block chain has a digital signature associated therewith that indicates the global block is from an authorized entity.
