AI Technical Summary

Technical Problem

In FTTR scenarios, the use of pre-configured authentication and encryption modes by slave devices during the initialization phase leads to inconsistencies in authentication and encryption modes across the entire network, affecting device security, terminal device energy consumption, and service stability.

Method used

The master device receives authentication and encryption capability information from the slave device and instructs it to use a specific authentication and encryption mode. It supports multiple compatible combinations of authentication and encryption modes and achieves unified configuration of authentication and encryption modes through WMCI message interaction.

Benefits of technology

It improves network security and configuration efficiency, avoids configuration conflicts caused by incompatibility between authentication and encryption methods, and ensures the normal operation and security of devices in different frequency bands.

Abstract

Provided in the present application are an optical network communication method and a communication apparatus. The method is applied to an optical fiber network, the optical fiber network comprising a master device and at least one slave device, wherein the at least one slave device includes a first slave device. In the method, during an initialization phase, after a master device receives an authentication and encryption capability of a slave device, the master device can indicate a determined authentication and encryption mode (e.g., a first authentication and encryption mode) to the slave device, so that in subsequent procedures (e.g., in a roaming parameter configuration procedure), the master device is no longer required to configure security-related parameters such as the authentication and encryption mode for the slave device, thereby facilitating an improvement in configuration efficiency and reducing configuration overhead.
