Abstract: This application discloses an identity authentication method, a device, and a system. The method includes: obtaining a first master public key and a first private key from a key generation center; sending a ClientHello message; obtaining a second identity from a ServerKeyExchange message; generating a pre-shared key of a selected PSK mode by using the second identity, the first private key, and the first master public key; and completing identity authentication with a second device by using the pre-shared key. According to the method, device, and system provided in embodiments of this application, an identity can be transmitted by using information in the TLS protocol, without extending the TLS protocol. This can avoid a compatibility problem caused by TLS protocol extension.

Abstract: 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.

Abstract: 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).

Abstract: An authentication method, an authentication apparatus, and an authentication system for the communications field are described. The authentication includes receiving, by a communications network element, a request from a user equipment (UE) comprising a first identifier that is an international mobile subscriber identity (IMSI). The communication networkelement, in response to the request, sends the first identifier to a home subscriber server. The communications network element, upon authenticating the UE successfully, sends a second identifier to a key management center (KMS) to facilitate the KMS generating a subscriber private key corresponding to the second identifier and sending the subscriber private key to the communications network element. The communications network element thereafter sends the subscriber private key to the UE.

Abstract: A key distribution method is disclosed. In this method, a key request can be received by a key management system (KMS) from a mobile operator network element (MNO). The key request can carry a public key of UE. At least one PVT and one SSK can be allocated to the US based on an IBC ID. The at least one PVT and SSK can be encrypted based on the public key to generate ciphertext; and an object can be signed based on a preset digital signature private key (DSPK) to generate a digital signature. The object can include the public key and the ciphertext. Still, a signature validation public key associated with the DSPK can be determined and a key response can be returned to the MNO. The key response can carry the signature validation public key, the public key of the UE, the ciphertext, and the digital signature.
