Registering client devices with a registration server |
摘要 |
In a method of registering a plurality of client devices with a device registration server for secure data communications, a unique symmetric key is generated for each of the client devices using a cryptographic function on a private key of the device registration server and a respective public key of each of the client devices, and a broadcast message containing the public key of the device registration server is sent to the client devices, in which the client devices are configured to generate a respective unique symmetric key from the public key of the device registration server and its own private key using a cryptographic function, and in which the unique symmetric key generated by each client device matches the respective unique symmetric key generated by the device registration server for the respective client device.
