Power Access Controller Authentication For Device Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Publicly accessible power outlets and chargers lack authentication and authorization, making it difficult to track and manage power consumption, leading to potential theft and inefficient resource allocation.
Innovation Solution
A method that involves receiving a power profile from a device indicating its expected consumption, authenticating and authorizing the device based on manufacturer, category, and power source capacity, and dynamically managing access to prevent overload and unauthorized use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If power outlets and chargers are made publicly accessible, then ease of operation is improved, but security and control over power consumption deteriorate
Solution Approach 1:
The system performs preliminary authentication and authorization checks before granting power access. Devices must present valid credentials and receive approval from the power management system before power flow is enabled, preventing unauthorized use while maintaining public accessibility
Solution Approach 2:
The system continuously monitors power consumption and compares it against expected values in the power profile. When deviations are detected, the system provides feedback by adjusting or terminating power supply, enabling real-time control and security enforcement
2Reliability
If authentication and authorization systems are implemented, then security and control are improved, but device complexity increases
Solution Approach 1:
The power management system performs multiple functions including authentication, authorization, power profiling, and consumption monitoring within a single integrated platform. This multi-functionality reduces the need for separate systems and minimizes overall complexity despite the advanced capabilities required
Solution Approach 2:
Devices automatically present their power profiles and credentials when connecting to the power system. The system self-authenticates and self-authorizes devices based on pre-configured parameters, eliminating the need for manual intervention and reducing operational complexity
3Measurement precision
If power consumption monitoring is implemented, then accounting accuracy is improved, but measurement and detection difficulty increases
Solution Approach 1:
The system pre-configures expected power consumption values and profiles for authorized devices before they connect. This preliminary data is stored and used as a reference for accurate measurement and comparison during actual power delivery, simplifying the measurement process
Solution Approach 2:
The system uses electrical field-based measurement techniques to detect and measure power consumption, replacing complex mechanical measurement methods. This substitution enables precise, non-intrusive monitoring of power flow and device consumption patterns
Data Source
AI summary
Systems and methods for authenticating, authorizing, and/or accounting for a power-consuming device to access a power source are described. A power access controller can manage the power source and authenticate and/or authorize the power-consuming device to access the power source based on, for example, a power profile of the power-consuming device. The power profile can indicate categories of devices for the power-consuming device, the manufacturer of the power-consuming device, and/or the device's expected power consumption. Accounting of an amount of power consumed by the power-consuming device can also be performed.
