Application: System and method for verifying memory integrity (Patent ID: US20240126454A1)
The patent filed by Hyundai Mobis Co Ltd. describes methods and apparatuses for ensuring the integrity of stored data in a flash memory. The system for verifying memory integrity includes a secure memory module, an integrity verifier, and a verification processor. The secure memory module stores key values for generating a message authentication code (MAC) value, the integrity verifier generates a MAC value based on an analysis of stored data and compares it with a stored MAC value, and the verification processor determines data manipulation and performs a preset operation if the MAC values do not match.
The patent further details a system for verifying memory integrity with various components such as an entire integrity verifier and a group integrity verifier. These components are responsible for generating MAC values for all data or specific main data groups, comparing them with stored MAC values, and detecting data manipulation. The method for verifying memory integrity involves generating MAC values using pre-stored processes, comparing them with stored values, and performing operations based on the comparison results. The method also includes steps for generating and storing MAC values for all data or main data groups, repeatedly performing group MAC generation and storage steps, and replacing manipulated data with default values. Overall, the patent outlines a comprehensive system and method for ensuring the integrity of stored data in a flash memory through the use of MAC values and key values stored in a secure memory module.
