Adaptive Encryption Switching for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile computing devices face challenges in dynamically adapting their security levels based on varying states, such as lock status, password protection, and location, to effectively balance security and performance.
Innovation Solution
The method involves determining the state of a mobile computing device and automatically switching between multiple security levels by selecting appropriate encryption algorithms, with each level offering progressively more electronic countermeasures and slower performance, using AES algorithms with varying amounts of countermeasures based on the device's state, such as being locked or unlocked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stronger encryption algorithms with more electronic countermeasures are used, then security level is improved, but processing speed deteriorates
Solution Approach 1:
The patent implements dynamic switching between different encryption algorithms based on the device's operational state. When the device is locked, stronger encryption with more electronic countermeasures is applied; when unlocked, weaker encryption is used. This dynamic adaptation resolves the contradiction by adjusting security strength to match actual security needs, improving speed when full security is not required while maintaining high security when needed.
Solution Approach 2:
The system changes encryption parameters (algorithm strength, countermeasure intensity) based on device state parameters such as lock status. By varying these parameters dynamically, the system achieves both high security when necessary and high performance when possible, resolving the trade-off between security strength and processing speed.
2Adaptability or versatility
If multiple encryption algorithms with varying countermeasures are implemented, then adaptability to different security contexts is improved, but device complexity increases
Solution Approach 1:
The patent segments the encryption system into multiple distinct algorithms, each optimized for specific security contexts. Rather than one complex adaptive algorithm, the system uses several simpler algorithms that can be selectively applied based on device state, achieving adaptability while managing complexity through modular design.
Solution Approach 2:
The encryption system is designed to perform multiple functions by selecting from different algorithms based on context. The same encryption framework handles both high-security locked states and lower-security unlocked states, providing universal security coverage across different operational modes without requiring separate systems for each state.
