Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing system-based security approaches are implemented to secure IoT devices, then security functionality is provided, but system complexity increases and scalability is reduced
Solution Approach 1:
The patent introduces a cloud-based security service platform as an intermediary between IoT devices. This platform provides centralized security management, authentication, and trust scoring services, allowing individual devices to remain simple while achieving robust system-wide security. The security functionality is offloaded from devices to the cloud intermediary.
Solution Approach 2:
The patent extracts security functionality from individual IoT devices and consolidates it into a separate cloud-based security service platform. This extraction removes the burden of complex security implementation from resource-constrained devices while maintaining comprehensive security coverage across the IoT ecosystem.
2Reliability
If security functionality is enhanced in each IoT device, then security is improved, but device complexity and resource requirements increase
Solution Approach 1:
The cloud-based security service acts as an intermediary that provides security functionality to devices without requiring the devices to implement complex security mechanisms themselves. Devices can remain simple while benefiting from the intermediary's security capabilities.
Solution Approach 2:
The patent implements a universal security service platform that serves multiple IoT devices with diverse security needs through a single centralized system. This multi-functional platform provides authentication, authorization, trust scoring, and security policy management for the entire IoT ecosystem rather than requiring each device to have dedicated security functionality.
3Quantity of substance
If the number of IoT devices increases, then system capability is improved, but security management complexity and performance degradation occur
Solution Approach 1:
The patent merges security management for all IoT devices into a single cloud-based security service platform. This consolidation allows the system to handle increasing numbers of devices through centralized management, avoiding the complexity that would arise from managing security for each device individually.
Solution Approach 2:
The patent implements dynamic trust scoring and adaptive authentication mechanisms that automatically adjust security levels based on device behavior and risk assessment. This dynamic approach allows the security system to efficiently manage large numbers of devices by applying appropriate security measures only when necessary, rather than applying uniform complex security to all devices.
Data Source
AI summary
An apparatus comprises a processing platform configured to communicate with a plurality of IoT devices over at least one network. The processing platform implements a security-as-a-service portal accessible to the IoT devices, the portal comprising an analytics engine configured to assign trust scores to respective ones of the IoT devices. The security-as-a-service portal provides authentication leveling functionality for the IoT devices based at least in part on the assigned trust scores. In accordance with the authentication leveling functionality, a first one of the IoT devices accesses the security-as-a-service portal to identify a level of authentication to be applied by the first IoT device in authenticating a second one of the IoT devices. The security-as-a-service portal may determine the authentication level to be applied by the first IoT device in authenticating the second IoT device based at least in part on the trust score assigned to the second IoT device.
