Abstract
A power saving method for lower-power devices is disclosed. Unencrypted IoT packets are received from low-power sensors. An identity of a mobile device is registered and public keys are exchanged between an MQTT agent and the mobile device. An advanced encryption standard (AES) key is generated according to public and private keys of the MQTT agent and a public key of the mobile device and received IoT packets are encrypted using the AES key. The encrypted IoT packets are transmitted to an MQTT broker. The MQTT broker forward the encrypted IoT packets to the mobile device. The mobile device exchanges the AES key with the electronic device according to its own public key through the secure shell (SSH) mechanism. The mobile device decrypts the IoT packets through the AES key.
