Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminal manufacturers face challenges in protecting their system data from unauthorized replication and ensuring secure access control, as existing solutions do not effectively prevent illegal replication and user access management.
Innovation Solution
A mobile terminal design featuring a singlechip with a 128-bits ID code and a master control module that performs irreversible secure hash calculations to authenticate user passwords and control access, using an Inter IC Bus or Serial Peripheral Interface for communication, ensuring only authorized users can access and operate system data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If system data is stored in a singlechip to prevent replication, then protection against illegal replication is improved, but access control and user authentication become more complex
Solution Approach 1:
The system divides the protection function into separate modules: a singlechip for storing system data and performing hash calculations, and a master control module for user authentication and access control. This segmentation allows each component to focus on specific tasks, reducing overall system complexity while maintaining strong protection.
Solution Approach 2:
The patent introduces a hash calculation intermediary mechanism that bridges the singlechip storage and the master control module. The singlechip performs irreversible secure hash calculations on system data, and the master control module verifies these hashes against user passwords, creating a secure intermediary layer that protects data without requiring direct access to the singlechip.
2Reliability
If irreversible secure hash calculation is performed on system data, then data security is improved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary hash calculation on system data during the initialization phase, storing the hash results in the singlechip. During user authentication, the master control module only needs to verify the provided password against the pre-stored hash values, significantly reducing the computational time required for each authentication operation.
Solution Approach 2:
Instead of storing the actual system data in the singlechip, the patent stores only the irreversible secure hash calculations of the system data. This copying approach allows the system to verify data integrity and authenticate users without repeatedly processing the full system data, reducing computational overhead while maintaining security.
3Reliability
If user password authentication is required for accessing system data, then access control is improved, but user convenience and operation speed decrease
Solution Approach 1:
The system implements self-service authentication where the singlechip automatically performs hash calculations on system data and compares them with the user's provided password. The master control module simply verifies the result and grants or denies access, reducing the burden on the user while maintaining strong authentication.
Solution Approach 2:
The patent replaces manual verification mechanisms with automated cryptographic hash calculation and comparison. Instead of requiring manual checking of system data integrity, the system uses irreversible secure hash functions to automatically verify data security and user authentication, significantly improving operational convenience while maintaining strong access control.
