Secure Resource Loading via Block-Level Verification

The patent divides the resource into multiple data blocks and verifies each block independently as it is loaded, rather than loading and verifying the entire resource at once. This segmentation allows verification to occur incrementally during the loading process, reducing the time the system waits for complete resource verification while maintaining security through block-level validation.

The patent implements partial verification by checking only the necessary data blocks that are actually needed for the current operation, rather than verifying the entire resource. The verification process performs exactly the minimal necessary actions (checking only required blocks) without excessive verification of unnecessary data, thereby reducing energy consumption while maintaining verification completeness for the needed portions.

The patent segments the resource verification into smaller block-level operations that can be performed efficiently during the loading process. This segmentation allows the system to work within the limited bandwidth of secure flash memory by verifying data in manageable chunks rather than requiring high-speed bulk verification, thus accommodating the bandwidth constraints while maintaining security through systematic block validation.

The patent implements preliminary verification of data blocks during the loading process itself, rather than requiring complete loading before verification can begin. This preliminary action approach allows verification to start as soon as the first blocks are loaded, overlapping the verification process with the remaining loading operations, thereby reducing startup time while ensuring system readiness through complete verification of necessary executables.
