Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current smartphones lack the ability to detect and mitigate vulnerabilities in cellular networks, forcing users to blindly trust their network service providers and mobile operating systems, which are ill-equipped to provide security indicators or defend against vulnerabilities in Layers 1 through 3 of cellular communications.

Innovation Solution

A system comprising a client device and a companion device that mirrors the client device's network connection, allowing the companion device to authenticate, observe potential vulnerabilities, and transmit information back to the client device for a vulnerability assessment, without requiring the client device to compromise its operating system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Difficulty of detecting and measuring

If users access radio-level traffic to detect network vulnerabilities, then detection capability is improved, but endpoint security is compromised through jailbreaking or rooting

Engineering Contradiction:

Improvenetwork vulnerability detection capabilityVSAvoidendpoint security

Core Design Contradiction:

Difficulty of detecting and measuringVSReliability

Solution Approach 1:

The patent introduces a companion device as an intermediary between the client device and the cellular network. The companion device receives network configuration parameters from the client device, wirelessly connects to the cellular network, authenticates using the same parameters, and observes network characteristics without requiring the client device to compromise its operating system. This mediator approach allows vulnerability detection while preserving endpoint security.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The companion device creates a mirror copy of the client device's network connection by receiving and replicating network configuration parameters. This copying allows the companion device to observe and report on network vulnerabilities from an independent perspective without requiring modifications to the client device's operating system, thus maintaining security while enabling detection.

Inventive Principle:

Principle #26Copying

2Object-affected harmful factors

If mobile operating systems obfuscate granular network telemetry to prevent malicious behavior, then security protection is improved, but user ability to verify network integrity is reduced

Engineering Contradiction:

Improveprotection against malicious behaviorVSAvoidnetwork integrity verification capability

Core Design Contradiction:

Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The companion device serves as an intermediary that bypasses the obfuscation barriers built into mobile operating systems. By connecting independently to the cellular network and receiving network configuration parameters through standard wireless interfaces, the companion device can access and report on network characteristics that remain hidden from users through API obfuscation, while the client device's operating system remains unmodified and secure.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If users trust network service providers without verification means, then ease of operation is improved, but security reliability is worsened

Engineering Contradiction:

Improvenetwork connection simplicityVSAvoidnetwork security trust

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system enables users to perform self-verification of network security characteristics through the companion device. Users can independently observe network characteristics, identify vulnerabilities, and receive reports about network security status without requiring technical expertise or compromising their devices. This self-service capability restores trust by providing transparent verification means while maintaining ease of operation.

Inventive Principle:

Principle #25Self-service

AI summary

Embodiments of the invention include systems and methods for assessing network security and integrity, and more particularly to detecting and mitigating vulnerabilities in communication networks. In embodiments, a client device connects wirelessly to a cellular network based on configuration parameters. A companion device mirrors the client device's connection to the cellular network based on the configuration parameters. The companion device observes at least one characteristic indicative of one or more vulnerabilities of the cellular network and communicates related information to the client device. The client device provides a vulnerability assessment based on the information.
