Abstract
A communication system includes an external device and a robotic garden tool. The external device is configured to generate a first key pair including a first private key for a robotic garden tool and a first public key for a server device. The external device transmits the first private key to the robotic garden tool, and transmits the first public key to the server device. The robotic garden tool is configured to receive an encrypted first instruction from the server device. The encrypted first instruction was encrypted by the server device using the first public key. The robotic garden tool is configured to decrypt the encrypted first instruction using the first private key to generate a decrypted first instruction. The robotic garden tool is configured to control operation of the robotic garden tool in accordance with the decrypted first instruction.
