Peripheral Sensor Initialization Before Authentication Delays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional sensor initialization processes in computing systems are delayed due to authentication occurring before initialization, which can hinder meeting performance criteria, such as displaying backup camera images within a certain time frame, and introduce additional computing resource overhead.
Innovation Solution
Perform initialization operations on peripheral devices before authentication, leveraging error-detection codes and message counters to verify device integrity and configuration during initialization, reducing the need for extensive secure communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication operations are performed prior to sensor initialization, then device security and data integrity are ensured, but initialization time is significantly delayed
Solution Approach 1:
The patent performs sensor initialization operations before authentication is complete. Specifically, the sensor is initialized to begin capturing images, and these images are captured and displayed even before the authentication process finishes. This preliminary action allows the system to meet performance criteria (displaying backup camera images within a certain time frame) while maintaining security through subsequent authentication verification.
2Reliability
If secure communications are used during initialization operations, then communication security is improved, but computing resource overhead and processing time increase
Solution Approach 1:
The patent performs initialization operations before authentication is complete, allowing the sensor to begin capturing and processing images without waiting for secure communication channels to be established. The system initializes the sensor, captures images, and displays them while authentication is still in progress, thereby improving initialization speed without completely eliminating security measures.
Solution Approach 2:
The patent applies authentication and secure communication measures selectively rather than uniformly to all initialization operations. Not all initialization steps require full authentication overhead, allowing the system to perform partial initialization without secure communications and apply security measures only where necessary to maintain adequate protection.

AI summary
Embodiments relate to applications, platforms, architecture, etc. for authenticating a peripheral device and initialization of the peripheral device. For example, one or more initialization operations may be performed with respect to the peripheral device prior to the peripheral device being authenticated. In these and other embodiments, the authentication may be based on information maintained during the initialization, such as error-detection code values and/or message counter values. Performing the authentication and initialization operations in the manner disclosed may reduce the amount of time used for authenticating and initializing peripheral devices as compared to authenticating first and then initializing as is typically done.
