Abstract: This application discloses a digital certificate verification method and apparatus. The method includes: A first device receives a first link certificate and a first digital certificate that are sent by a second device, and verifies validity of the first digital certificate based on a root certificate trusted by the first device and the first link certificate. In this application, the first device and the second device do not need to confirm a root certificate trusted by a peer device, and the first device does not need to additionally upload another certificate or perceive a case in which at least two root certificates coexist. The first device may verify the validity of the first digital certificate based on the root certificate trusted by the first device and the received first link certificate. Therefore, the method is simple and easy to implement and has a wide application scope.

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: This document describes a system and method for generating a common session key for encoding digital communications between devices. In particular, the system allows two devices to verify the veracity of each device before these authenticated devices proceed to generate a common session key that is then utilized to encode digital communications between these two devices.

Abstract: A temporary MAC address-based access method, apparatus, and system is provided. A method includes performing wireless communication access authentication on a base station for a non-base station device (STA) by sending, from the base station to the STA, a message indicating whether the base station supports the STA in using a temporary MAC address (TMA), receiving, at the base station, an authentication message in response to the message. The authentication message is sent by the STA to the base station by using the TMA in response to determining that the message indicates that the base station supports the STA in using the TMA. The method further includes parsing out the TMA by using the authentication message and sending an authentication response message to the STA according to the authentication message. The authentication response message indicates whether the base station allows the STA to use the TMA for communication.
