UEFI VARIABLE STORAGE SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240346187 titled 'UEFI VARIABLE STORAGE SYSTEM
Simplified Explanation: The UEFI variable storage system described in the patent application includes a subsystem for UEFI variable services connected to UEFI variable sources, a trusted UEFI variable storage subsystem, and an untrusted UEFI variable storage subsystem. When the UEFI variable services subsystem receives a UEFI variable during an initialization process and determines whether it has reached a certain point, it stores the variable in either the trusted or untrusted storage subsystem accordingly.
- The UEFI variable storage system consists of a UEFI variable services subsystem, trusted UEFI variable storage subsystem, and untrusted UEFI variable storage subsystem.
- The system stores UEFI variables based on the progress of the initialization process.
- Variables are stored in the trusted subsystem if the initialization process has not reached a specific point, and in the untrusted subsystem if it has.
Potential Applications: 1. Secure storage of UEFI variables during system initialization processes. 2. Enhanced security measures for firmware updates and configurations.
Problems Solved: 1. Ensuring secure storage of UEFI variables during system initialization. 2. Managing the storage of variables based on the progress of the initialization process.
Benefits: 1. Improved security for UEFI variables. 2. Efficient management of variable storage during system initialization.
Commercial Applications: Secure boot systems, firmware updates, embedded systems security.
Prior Art: Research on UEFI variable storage systems and secure boot mechanisms in firmware.
Frequently Updated Research: Stay updated on advancements in UEFI variable storage systems and secure boot technologies.
Questions about UEFI Variable Storage System: 1. How does the UEFI variable services subsystem determine the progress of the initialization process? 2. What are the potential implications of storing UEFI variables in both trusted and untrusted storage subsystems?
Original Abstract Submitted
a uefi variable storage system includes a uefi variable services subsystem coupled to uefi variable sources, a trusted uefi variable storage subsystem, and an untrusted uefi variable storage subsystem. if the uefi variable services subsystem receives a first uefi variable during a first uefi initialization process from a first uefi variable source and determines that the first uefi initialization process has not reached an untrusted uefi variable source point, it stores the first uefi variable in the trusted uefi variable storage subsystem. if the uefi variable services subsystem receives a second uefi variable during the first uefi initialization process from a second uefi variable source and determines that the first uefi initialization process has reached the untrusted uefi variable source point, it stores the second uefi variable in the untrusted uefi variable storage subsystem.
