Abstract: Internet of Things (IoT) system and method of interfacing arbitrary non-network connected devices to wireless computer networks. The invention provides a configurable wireless communications module, in either fixed or removable formats, with wireless (e.g. WiFi) network connectivity. The invention uses at least one internal processor, which is configured to operate as a sandbox or virtual machine manner to isolate the code used to operate the arbitrary non-network connected device from the code used to operate the communications module.

Abstract: An Internet of Things (IoT) device is deployed with embedded software. A debug client device stores an end-to-end encryption key that corresponds to an end-to-end encryption key stored on the IoT device. The debug client encrypts a debug instruction using the end-to-end encryption key and encrypts additional data using a point-to-point encryption key. The encrypted debug instruction and the encrypted additional data are sent to a debug server over a network. The debug server decrypts the additional data and identifies the IoT device from among multiple IoT devices. The debug server generates a message to the IoT device including the encrypted debug instruction, encrypts the message, and transmits the message to the IoT device. The IoT device decrypts the message using a first decryption key associated with the debug server, retrieves the encrypted message payload, and decrypts the message payload using the stored end-to-end encryption key.

Abstract: An Internet of Things (IoT) device is deployed with embedded software that may comprise multiple components. After deployment, updated versions of one or more components of the embedded software may become available. The IoT device maintains a manifest of the installed components. Periodically, the IoT device requests an updated copy of the manifest from an upgrade server. The installed manifest and the updated manifest are compared to determine if updated versions of any components are available. If so, the IoT device requests only the components to be updated. Prior to beginning the copying of the upgraded components, an upgrade flag is set. The IoT device then begins copying the received components into memory, replaces the manifest with the updated manifest, and clears the upgrade flag.
