Secure Debug Access for ADAS Cache and Sensor Processing

The patent extracts the debug port functionality from the main system and implements it as a separate, controlled access mechanism. The debug port is isolated with its own authentication subsystem, allowing debugging capabilities to be maintained while preventing unauthorized access to the core ADAS and AV systems. This separation enables independent control of debugging access without compromising overall system security.

The patent introduces an intermediary authentication mechanism between the debug port and the system resources. This intermediary layer verifies credentials and controls access to debugging functions, acting as a mediator that allows legitimate debugging while blocking unauthorized access. The authentication subsystem serves as the intermediary that reconciles the need for debugging access with the requirement for system security.

The patent segments the access control mechanism into distinct modular components: authentication subsystem, credential verification module, and access decision logic. This segmentation allows each component to be independently implemented and managed, reducing overall system complexity while maintaining comprehensive data security. The modular structure enables selective deployment of security features based on specific data protection requirements.

The patent implements a universal authentication framework that serves multiple security functions simultaneously. The same access control mechanism protects debug ports, data access, and system configuration, eliminating the need for separate security implementations for each function. This multi-functional approach reduces system complexity by consolidating security operations into a single versatile subsystem.
