IoT API Authentication via Network TCP Flow Logging

The patent introduces an intermediary authentication mechanism that mediates between IoT devices and the cloud platform. The system captures TCP flow data, extracts packet information, and validates API calls through an intermediate authentication process rather than implementing complex security measures directly in each device. This intermediary layer handles the security complexity centrally while keeping individual devices simpler.

The patent creates a copy of the TCP flow data and packet information for validation purposes. Instead of modifying the actual API call flow or implementing complex security protocols in devices, the system captures and validates copies of the communication data. This allows security verification without adding complexity to the original device operations.

The patent performs preliminary actions by capturing and logging TCP flow data as it naturally occurs during device communication. The system prepares the validation data in advance by monitoring the TCP stream, so when API calls need validation, the necessary packet information is already captured and ready for comparison. This preliminary data capture reduces the time needed for actual validation.

The patent replaces complex mechanical security verification systems with a lighter-weight validation approach. Instead of implementing heavy cryptographic protocols or multi-step authentication mechanisms, the system substitutes a simpler validation method that compares packet information against captured TCP flow data. This substitution reduces processing time while maintaining security effectiveness.
