Trusted Device Detection for Processing Unit Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer systems, including autonomous vehicles and critical infrastructure, are vulnerable to malicious hacking, leading to data breaches and service disruptions, necessitating robust security protocols to prevent unauthorized access.
Innovation Solution
A method of securing processing units by detecting and verifying trusted devices through wireless communication, such as Bluetooth, and ensuring only registered and verified devices can access the system, with additional identity verification for users, and periodic re-verification to maintain access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional access control methods are used, then ease of operation is maintained, but system security against malicious hacking is insufficient
Solution Approach 1:
The system performs preliminary actions by pre-registering trusted devices and storing their identifiers in a database before actual access attempts occur. When a user tries to access the system, the processor automatically queries the database to verify if the device is trusted, eliminating the need for complex real-time security decisions and providing seamless access for authorized users while blocking unauthorized ones.
2Reliability
If device detection and verification protocols are implemented, then unauthorized access is prevented, but device complexity increases
Solution Approach 1:
The patent extracts the complex security verification logic from the access control decision-making process and places it in a separate database component. The processor simply queries the database for device trust status rather than implementing complex verification algorithms, thereby reducing the computational complexity of the main processing unit while maintaining robust security through the dedicated database verification system.
