Abstract
A secure connection between a user mobile device and a “Internet-of-Things” network-connected device (e.g., a home appliance or a vehicle) may be provided using an internet gateway residing in the public internet and a local gateway residing in a private network behind a firewall. The user device may receive an input through a software application and may generate an electronic instruction based on the input. The user device may then encrypt the electronic instruction and send the encrypted electronic instruction to the internet gateway over a secure connection (e.g., SSH, TLS). The internet gateway then sends the encrypted electronic instruction to the local gateway, which decrypts the encrypted electronic instruction, interprets it, and generates and transmits a device instruction to communicate with the network-connected device, either directly or through an intermediary device such as a third-party bridge or hub. Only the user device and local gateway have encryption/decryption keys.
