Solution Overview
Problem
IoT networks face challenges in achieving consistent security capabilities across heterogeneous devices due to varying security parameters and limited resources in constrained environments, leading to interoperability gaps, including security interoperability issues.
Innovation Solution
Implementing a Software Defined Network Security Interoperability (SDNSI) solution with a Security Resource Introspection Manager (SRIM) that analyzes security attributes of IoT devices, constructs connectivity graphs, and provides recommendations or isolates devices to ensure secure communication paths, using mechanisms like directory services, inference engines, and dynamic provisioning to align security settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security capabilities are enhanced across IoT devices, then network security is improved, but device complexity and resource requirements increase
Solution Approach 1:
The patent introduces a Security Gateway as an intermediary component that centralizes security management functions. The gateway analyzes security attributes, constructs connectivity graphs, and determines interoperability paths, thereby enhancing network security without requiring complex security implementations in individual constrained IoT devices. The gateway acts as a mediator that handles the computational burden of security analysis externally.
Solution Approach 2:
The Security Gateway performs multiple functions including security attribute analysis, connectivity graph construction, interoperability path determination, and device provisioning. By consolidating these diverse security management tasks into a single multi-functional gateway, the system improves overall network security while avoiding the need to implement all these complex functions in each individual IoT device.
2Reliability
If security interoperability is ensured across heterogeneous devices, then communication reliability is improved, but system complexity increases
Solution Approach 1:
The Security Gateway serves as a central intermediary that manages security interoperability across heterogeneous IoT devices. It analyzes security attributes from different devices, constructs a connectivity graph representing security relationships, and determines appropriate interoperability paths. This centralized mediation approach ensures reliable communication between diverse devices without requiring each device to independently handle complex interoperability logic.
Solution Approach 2:
The system dynamically determines security parameters and interoperability configurations based on the analyzed security attributes of participating devices. The Security Gateway adjusts security settings, protocol selections, and communication paths by changing parameters in response to the specific capabilities and requirements of each device pair, thereby ensuring reliable communication while adapting to heterogeneity.
3Measurement precision
If security analysis is performed on all devices, then interoperability issues are identified, but processing time and computational resources increase
Solution Approach 1:
The Security Gateway performs security attribute analysis and connectivity graph construction in advance, before actual device communication is needed. By pre-analyzing security attributes and pre-determining interoperability paths, the system identifies potential interoperability issues ahead of time without causing delays during actual device operations. This preliminary analysis approach ensures accurate interoperability detection while minimizing processing time during runtime.
