Hot Update Agent Thread for Android Framework Vulnerability Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Android operating system's framework vulnerabilities cannot be effectively repaired using existing hot update mechanisms, leading to security threats due to fragmentation across various devices and a lengthy repair cycle.
Innovation Solution
A hot update method is introduced that creates a hot update agent thread to dynamically repair system processes in real-time by invoking a patch repairing framework, allowing for framework updates without restarting the operating system, thereby addressing vulnerabilities and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional system update methods are used to repair framework vulnerabilities, then security can be improved, but the repair cycle becomes too long and devices cannot be updated uniformly
Solution Approach 1:
The patent segments the framework update process into two distinct parts: hot patches that can be applied immediately to repair vulnerabilities, and full system updates for comprehensive changes. This segmentation allows security patches to be deployed independently and rapidly across devices without waiting for complete system update cycles, directly resolving the contradiction between security improvement and repair time.
Solution Approach 2:
The patent implements preliminary action by pre-compiling and preparing hot patches in advance with proper verification mechanisms. The hot patch verification module checks patches before deployment, and the hot update agent is pre-installed on devices to receive and apply patches immediately upon arrival, eliminating the need for lengthy operator audit and user download phases traditional updates require.
2Reliability
If framework updates are pushed through version upgrades, then vulnerabilities can be repaired, but device fragmentation increases and uniform updates become difficult
Solution Approach 1:
The patent creates a universal hot patch delivery mechanism that can be deployed across diverse Android device versions and manufacturers. The hot update agent thread is designed to work with the Android runtime environment universally, and the verification module ensures compatibility before deployment. This allows the same vulnerability patch to be applied uniformly across different device types without requiring device-specific version upgrades, resolving the contradiction between vulnerability repair and device uniformity.
3Productivity
If hot update mechanisms are applied to the framework layer, then repair speed can be improved, but system stability may be compromised
Solution Approach 1:
The patent implements a feedback mechanism through the hot patch verification module that checks and validates hot patches before they are applied to the framework. The verification module analyzes patch integrity, compatibility, and safety, providing feedback that determines whether a patch should be deployed. This feedback loop ensures that only verified, safe patches are applied, maintaining system stability while enabling rapid repair through hot updates.
Data Source
AI summary
A hot update method, an operating system, a terminal device, and a storage medium are provided according to embodiments. The method includes: receiving startup information of a system process sent by a hot update agent thread; checking a hot patch corresponding to the system process, in response to the startup information; and sending a patch processing request to the hot update agent thread, so as to request the hot update agent thread to invoke a patch repairing framework in response to the patch processing request. The embodiments can implement hot update of the framework and protect the security of the entire Framework layer and the APP layer.
