Dual Mode Wireless Secure Lock Authentication

The patent introduces a dual-mode authentication system that operates across two different communication dimensions: NFMI (near-field magnetic induction) for secure authentication and RF (radio frequency) for keyless operation. This multi-dimensional approach allows the system to achieve both high power transfer efficiency through magnetic induction and relaxed alignment requirements through alternative communication paths.

The patent employs an intermediary authentication mechanism using NFMI communication that mediates between the power transfer system and the authorization system. This intermediary layer verifies credentials before enabling operation, allowing the magnetic induction system to operate at optimal efficiency without requiring precise alignment, as the authentication occurs through the magnetic field coupling regardless of exact positioning.

The patent segments the authentication system into two distinct communication modules: NFMI for secure credential verification and RF for keyless access. Each module operates independently with its own protocol and security layer, allowing the system to achieve enhanced security through multiple authentication paths while managing complexity through modular design. The key controller contains separate processing logic for each communication type.

The patent implements a universal key controller that can operate across multiple communication protocols (NFMI and RF) and multiple operation modes (authenticated and keyless). This multi-functional design consolidates what could be separate systems into a single integrated device, achieving high security through protocol diversity while reducing overall system complexity through component consolidation.

The patent implements preliminary action by pre-storing authentication credentials (passcodes, encrypted keys) in the key's memory before the authentication event occurs. When authentication is required, the system retrieves and compares these pre-stored values against received signals, significantly reducing processing time compared to real-time computation. The heavy cryptographic work is performed in advance during key provisioning.

The patent employs periodic action through timeout mechanisms and structured authentication sequences that limit the time window for each authentication attempt. The system uses defined time intervals for credential verification, keyless operation validation, and session management, ensuring that while security checks are thorough, the overall processing time remains bounded and predictable through periodic operation cycles.
