AI Technical Summary

Technical Problem

The installation of a new device in a communication network poses security risks for data related to this installation, particularly during the association phase when the new device communicates with the network control system.

Method used

An association process between a bridge and a device is implemented, where the bridge generates a unique identifier for the device and encrypts a message containing an encryption key using a code specific to the device. This encrypted message is then disseminated on the communication network, ensuring secure communication during the association and subsequent data exchanges.

Benefits of technology

The proposed solution ensures secure exchanges during the association process and subsequent data transmissions by using a unique encryption key specific to each device, thereby mitigating the risks associated with data security during device installation in communication networks.

Abstract

A method for associating a gateway (101) with a device (103a-c) is described, the device's memory containing a device-specific code. The method includes reading (201) the device's specific code and providing (202) the device's specific code to the gateway; the generation (203) by the gateway of an encryption key and a device identifier; the encryption of a message containing the encryption key and the identifier, the encryption being a function of the device's specific code, and the dissemination of the encrypted message; the reception and decryption, by the device, of the encrypted message; the encryption, by the gateway, of the data to be transmitted using the encryption key; and the point-to-point transmission, by the gateway to the device, using the identifier, of the encrypted data.
