Boot Authentication Startup Module Network Stack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security measures for computing devices are vulnerable to attacks that compromise the BIOS before the device has completed boot operations, allowing unauthorized access and data theft.
Innovation Solution
Implementing a startup module that loads a network stack during the boot phase without RAM resources to authenticate with an authentication server, preventing device operation if authentication fails, and taking security actions such as erasing data or alerting the server to protect the device and its data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security measures are implemented during normal operation, then security is improved, but the device remains vulnerable to attacks during the boot phase before security measures are activated
Solution Approach 1:
The patent implements authentication and security verification during the boot phase, before the operating system and vulnerable components are fully loaded. The startup module performs network authentication and verifies device integrity early in the boot process, preventing unauthorized access before security vulnerabilities can be exploited. This preliminary security action resolves the contradiction by establishing security before normal operation begins, rather than relying solely on post-boot security measures.
2Reliability
If authentication is performed during boot phase without RAM resources, then security is improved, but device complexity increases
Solution Approach 1:
The patent divides the boot process into distinct phases with specific security functions. A dedicated startup module is created that operates independently during the early boot phase, handling network stack initialization and authentication. This segmentation allows security-critical operations to be isolated from the main boot process, reducing the attack surface while maintaining security. The modular approach manages complexity by creating a focused authentication subsystem rather than integrating security throughout the entire boot process.
Solution Approach 2:
The patent introduces a startup module as an intermediary component that mediates between the hardware boot process and the operating system. This intermediary handles network authentication and security verification, acting as a buffer that prevents direct access to vulnerable system components during boot. The intermediary approach simplifies the overall system architecture by centralizing security functions in a dedicated component rather than distributing complexity across multiple subsystems.
3Reliability
If the device is prevented from operating when authentication fails, then security is improved, but loss of time occurs due to boot interruptions
Solution Approach 1:
The patent implements a feedback mechanism where the startup module continuously monitors authentication status and device integrity during the boot phase. If authentication succeeds and no security threats are detected, the system provides feedback to proceed with normal boot operations. If authentication fails or threats are detected, feedback triggers security responses such as halting the boot process or entering a secure state. This feedback-based approach ensures that productivity is maintained when security conditions are met, while automatically enforcing security restrictions when conditions are not met.
Data Source
AI summary
Examples associated with boot authentication are described. One example includes initiating a power on self-test (POST) phase of a boot of a system. Prior to initiating a driver execution environment phase of the POST phase, a network stack may be loaded for a network port. An encrypted key may be retrieved from a trusted component of the system. Boot of the system may be permitted to proceed upon establishing a connection with an authentication server, and authenticating the system to the authentication server based on the encrypted key.
