IoT Message Broker Protocol Wrapping for Secure Remote Access

The patent introduces a message broker as an intermediary component that sits between the external network and IoT devices. The broker receives messages from external users, validates them against security policies, and forwards approved messages to the appropriate IoT devices. This mediator approach maintains security and reliability while avoiding the complexity of full VPN implementations, as the broker handles connection management centrally rather than requiring individual VPN client installations on each device.

The patent implements a self-service message broker system that can be deployed and configured by the organization itself rather than relying on external cloud providers. The broker uses open standards and protocols, allowing the organization to maintain full control over the access mechanism. This self-hosted approach eliminates utilization restrictions imposed by cloud service business models and avoids the complexity of integrating with proprietary cloud channel technologies, while still providing convenient remote access capabilities.

The patent extracts the security and connection management functionality from the IoT devices themselves and places it in a centralized message broker. Instead of requiring each IoT device to run VPN client software or security agents, the broker handles all security validation, authentication, and message routing centrally. This extraction reduces the performance requirements and maintenance burden on individual IoT devices while maintaining strong security controls through the broker's centralized policy enforcement.
