    摘要: This application discloses a Wi-Fi security authentication method and a communication apparatus. In the method, an access point AP receives a first access request from a supplicant, where the first access request carries a first parameter, and the first parameter is a parameter generated by the supplicant based on a generator of a set cyclic group and a first random number; generates a second random number, generates a second parameter based on the second random number and the generator of the set cyclic group, and sends the second parameter to the supplicant, so that the supplicant generates a first pairwise master key based on the second parameter; generates a second pairwise master key based on the second random number, the first parameter, the second parameter, and a first target random key, where the first target random key is a random key newly allocated to the supplicant; and performs a four-way handshake authentication procedure with the supplicant based on the first pairwise master key and the second pairwise master key. The method can reduce a security risk caused by key leakage, and improve network security.

    摘要: A smart lock unlocking method and a related device are provided, and may be specifically applied to an intelligent vehicle and a self-driving vehicle, to implement an unlocking function of a smart lock of the vehicle. The method includes: A terminal device monitors a distance change trend between the terminal device and an intelligent device, where the intelligent device includes a smart lock (S401). If the terminal device determines that the terminal device is approaching the intelligent device and a distance between the terminal device and the intelligent device is less than a first distance threshold, the terminal device enables an identity authentication process between the terminal device and the intelligent device (S402). The terminal device unlocks the smart lock when identity authentication between the terminal device and the intelligent device succeeds (S403). The method may be applied to a plurality of technical fields such as intelligent driving, smart household, and smart buildings, and is used to implement intelligent and secure unlocking of a vehicle device or a door status control device.

    摘要: Embodiments of this application disclose an address generation method, a blockchain information processing method, and a related device, which may be used in the blockchain field. The method includes: a first blockchain node generates a shared key based on a private key of a first blockchain node and a first public key of a second blockchain node, generates a temporary first public key address of the second blockchain node based on the shared key and first transaction content, and writes first transaction information into a blockchain, where the first transaction information includes a public key address of the first blockchain node, the first public key address, and first transaction content between the first blockchain node and the second blockchain node; and the first public key address needs to be verified by using the shared key, and a recipient may also generate the shared key by using a public key of the first blockchain node and a first private key of the second blockchain node, to verify the transaction information. The recipient does not need to store or manage a plurality of public-private key pairs, thereby simplifying management.

    摘要: Embodiments of the present invention disclose a device upgrade method and a related device, which may be specifically applied to an intelligent vehicle and a driverless vehicle, to ensure upgrade security of a vehicle-mounted device in the vehicle. The method includes: A control device receives first upgrade file data sent by a communications device, where the first upgrade file data is upgrade file data generated after the communications device performs first security processing on an upgrade file by using a first key. The control device performs second security processing on the first upgrade file data by using a second key, to generate second upgrade file data, and sends the second upgrade file data to a to-be-upgraded device. The to-be-upgraded device receives the second upgrade file data, performs security verification on the second upgrade file data by using a corresponding verification key, and performs upgrade by using the upgrade file if the verification succeeds. This application may be applied to a plurality of technical fields such as a smart home and smart driving, to ensure secure and efficient upgrade of a home device or a vehicle-mounted device.

    摘要: A camera authentication method and a control apparatus are provided, and are applicable to an identity authentication of an on-board camera in the autonomous driving field. The method includes: obtaining one or more frames of a first image shot by a to-be-authenticated camera; determining one or more light intensity offset values of N photosensitive units based on the one or more frames of the first image; determining a matching degree between the light intensity offset values of the N photosensitive units and a preset N-dimensional vector; and if the matching degree meets a preset condition, determining that authentication of the to-be-authenticated camera succeeds, where the N photosensitive units are in a photosensitive layer of the to-be-authenticated camera, and the photosensitive layer includes M photosensitive units, where N≤M. This technical solution is used to improve camera security.

    摘要: This application relates to an identity verification method and an apparatus, and may be applied to an internet of vehicles, for example, V2X, LTE-V, or V2V A first apparatus sends a first random number to a second apparatus. A first vehicle carries the first apparatus and a first set. The second apparatus belongs to the first set. The first set further includes a third apparatus. The first apparatus communicates with the third apparatus by using the second apparatus. The first apparatus receives a first message from the second apparatus. The first message includes first verification information. The first verification information is used to perform identity verification on the second apparatus. The first verification information is generated based on identity information of the second apparatus and the first random number. The first apparatus determines, based on the first verification information and the first random number, that the identity verification on the second apparatus succeeds. In a hierarchical verification manner, identity verification can be performed on each level of vehicle-mounted devices.

    摘要: Embodiments of this application provide an information transmission method, a communications device and system, and a computer-readable storage medium, and are applicable to information exchange inside an intelligent vehicle in the field of autonomous driving. In the embodiments of this application, a full counter value maintained by each ECU device includes a global counter value and a local counter value. The global counter value keeps globally synchronized in an entire CAN network, and the local counter value is obtained by each device performing counting by using a local counter. In this way, when a second device sends a CAN message, the CAN message carries a second counter value. When receiving the CAN message, the first device may determine whether a locally maintained first counter value matches the second counter value. If the locally maintained first counter value does not match the second counter value, the CAN message may be verified by using the second counter value and the global counter value. In this way, the technical solutions provided in the embodiments of this application can improve security and stability of an in-vehicle network of the intelligent vehicle.
