Abstract
A robust device messaging framework is disclosed that enables a user to send commands to a device. A provisioning service is used to provision unique device identities and maps user web identities to device identities. The provisioning service also limits device per day provisioning attempts to limit denial of service attacks. A command service allows remote users to issue commands to a device, synchronize outgoing commands with incoming results, receive accurate feedback about whether a command was received, and maintain state information about the device. A device layer encrypts and stores device identities, authenticates itself with the command service, establishes a high-availability Internet connection to receive alerts that a command has issued, and reports results to the server-based command service.
