Microprocessor Configuration Logging with Manipulation-Proof Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for configuring microprocessor systems require semiconductor manufacturers to manage and distribute multiple release codes, leading to logistical and financial burdens due to the need for customers to configure microprocessor systems, which can be manipulated, making it difficult for manufacturers to accurately bill based on selected configurations.
Innovation Solution
An apparatus with a security module for creating a manipulation-proof log that securely logs configuration parameters, allowing semiconductor manufacturers to generate release codes and ensure secure communication and storage of configuration data, preventing manipulation and enabling accurate billing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple release codes are distributed for configuration-dependent billing, then customers can configure microprocessor systems with different system properties and memory sizes, but the semiconductor manufacturer must manage and distribute a multiplicity of release codes around the clock, entailing large logistical effort and high costs
Solution Approach 1:
The logging apparatus is pre-installed in the microprocessor system with a security module that generates and stores release codes locally. This preliminary setup eliminates the need for ongoing distribution of release codes, as the system can autonomously manage configuration and billing information without external intervention.
Solution Approach 2:
The microprocessor system with integrated logging apparatus serves itself by autonomously logging configuration parameters and generating release codes locally. The system performs its own configuration management and billing information storage without requiring external support from the semiconductor manufacturer, reducing logistical burden.
2Device complexity
If the semiconductor manufacturer leaves logging of configurations entirely to the customer, then the manufacturer avoids logistical effort, but the manufacturer is exposed to manipulation risk and cannot securely obtain configuration information for billing
Solution Approach 1:
The security module within the logging apparatus acts as an intermediary between the customer's configuration actions and the manufacturer's billing system. It securely logs configuration parameters and generates release codes, ensuring that configuration information is accurately recorded and cannot be manipulated, while still simplifying the manufacturer's role.
Solution Approach 2:
The system uses a disposable security module with a fixed storage area for release codes. This single-use security component ensures configuration integrity without requiring ongoing complex security infrastructure or manual intervention from the manufacturer, providing reliable logging with minimal operational overhead.
3Device complexity
If generic microprocessor systems with maximum configuration are delivered, then storage and logistics costs are reduced, but the customer must retrieve and enter release codes in good time, creating logistical burden for the customer
Solution Approach 1:
The logging apparatus with security module is pre-installed in the microprocessor system at the time of delivery. This preliminary configuration allows the system to automatically log configuration parameters and generate release codes without requiring the customer to manually retrieve or enter codes, simplifying the configuration process while maintaining inventory efficiency.
