Lightweight Anti-Malware Client for Mobile Hotspot Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile computing devices, especially those without 3G capability, are vulnerable to security threats when connecting to the Internet via WiFi hotspots due to limited compatibility and computing power, making it difficult to deploy and maintain anti-malware protection.
Innovation Solution
A mobile phone with wireless hotspot capability serves as a bridge, using a lightweight anti-malware client to screen network traffic by forwarding identifying characteristics to a cloud security network for evaluation, thereby protecting connected devices without the need for individual anti-malware installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anti-malware is deployed on mobile computing devices, then security protection is improved, but device compatibility and resource requirements worsen
Solution Approach 1:
The patent introduces a gateway server as an intermediary between the mobile computing device and the network. The gateway server runs the anti-malware software and performs security screening on network traffic, while the mobile device only needs lightweight client software. This mediator approach resolves the contradiction by centralizing the resource-intensive security functions on the gateway while maintaining broad device compatibility through the lightweight client.
2Reliability
If traditional anti-malware is deployed on mobile computing devices, then security protection is improved, but computational resource requirements worsen
Solution Approach 1:
The patent segments the anti-malware system into two parts: a lightweight client on the mobile device that handles basic functionality, and a full-featured anti-malware engine on the gateway server that performs complex analysis. This segmentation allows the mobile device to maintain security protection while avoiding the computational burden of running complete anti-malware software locally.
Solution Approach 2:
The gateway server acts as an intermediary that handles the computationally intensive anti-malware operations. The mobile device communicates with the gateway, which performs the heavy lifting of malware detection and analysis, thereby resolving the contradiction between security protection and computational resource requirements.
3Reliability
If traditional anti-malware is deployed on mobile computing devices, then security protection is improved, but deployment complexity and maintenance burden worsen
Solution Approach 1:
The gateway server serves as a centralized intermediary that manages all anti-malware operations, updates, and configurations. This centralization simplifies deployment because administrators only need to configure the gateway once, and all connected devices automatically benefit from the security protection without requiring individual setup or maintenance.

AI summary
A mobile computing device, such as a mobile phone, serves as a wireless hotspot for other mobile computing devices. The other mobile computing devices connect to the mobile phone over a wireless computer network, and the mobile phone connects to the Internet over a mobile phone network. The wireless computer network may be a WiFi network and the mobile phone network may be a 3G network. The mobile phone may include a lightweight anti-malware client for screening network traffic between the other mobile computing devices and web servers on the Internet. The lightweight anti-malware client may consult a cloud security network for reputation of data included in the network traffic.
