Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks face challenges in dynamically selecting appropriate encryption protocols based on varying operating conditions across different access points and service providers, leading to potential reductions in network quality and functionality.
Innovation Solution
A rule set for client-applied encryption is deployed by a network device, allowing client devices to monitor operating conditions and select the appropriate encryption protocol for secure connections, persisting across multiple sessions and varying communication protocols and access points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed encryption protocol is used across all network conditions, then implementation simplicity is maintained, but network quality and functionality deteriorate under varying operating conditions
Solution Approach 1:
The patent implements dynamic encryption protocol selection by enabling client devices to automatically choose from multiple encryption protocols (e.g., WEP, WPA, WPA2, AES) based on real-time monitoring of network operating conditions. This transforms the static encryption approach into a dynamic system that adapts to changing environmental factors such as network type, security requirements, and service provider policies, thereby resolving the contradiction between implementation simplicity and network quality.
2Reliability
If multiple encryption protocols are supported and dynamically selected, then network quality and security are improved, but device complexity increases
Solution Approach 1:
The patent implements self-service by enabling client devices to autonomously monitor their own operating conditions and automatically select appropriate encryption protocols without requiring manual configuration or complex centralized management. The device independently evaluates network type, security requirements, and other operating conditions to make encryption protocol selections, thereby improving network security while minimizing the complexity burden on users and administrators.
3Adaptability or versatility
If encryption protocols are adapted to varying operating conditions, then network functionality is enhanced, but the complexity of detecting and measuring operating conditions increases
Solution Approach 1:
The patent implements multi-functionality by designing the operating conditions monitoring system to simultaneously detect multiple parameters (network type, security requirements, service provider policies, device capabilities) using a unified monitoring framework. This universal approach allows the system to gather comprehensive information about the operating environment through integrated monitoring, thereby enhancing network functionality while managing the complexity of detecting and measuring multiple operating conditions through a consolidated system.

AI summary
A rule set for client-applied encryption is created and deployed to a client device by a network device over a communications network. Encryption applied by the client in accordance with the rule set may form the basis of a secure connection in which encrypted information is encapsulated and tunneled across a network that includes a wireless or wired interface through which the client obtains network connectivity. The client may monitor operating conditions, including operating conditions of the communications network, client device, and/or service provider. The rule set includes one or more rules that may be used by the client in combination with the detected operating conditions to select the appropriate encryption protocol. The rule set may persist at the client for use over multiple sessions in which a range of communication protocols and/or access points are used by the client to obtain network connectivity.
