Title:
DATA PROTECTION METHOD FOR CHIP REWRITING EQUIPMENT, ELECTRONIC EQUIPMENT AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/000510
Kind Code:
A1
Abstract:
The invention discloses a data protection method for chip rewriting equipment. The method comprises the steps of data reading, data verification, data matching and data update, wherein when the equipment is powered on, by verifying data in an off-chip memory, the equipment compares the verification result with data stored in an on-chip nonvolatile memory; when the data is equal, the equipment copy the data in the off-chip memory to a mirror unit of an on-chip volatile memory, and an application program reads the data from the on-chip volatile memory and continues to execute the data, and writes the execution result into the off-chip memory; and the execution result is written into the on-chip nonvolatile memory after being processed through a verification algorithm. The invention furthermore relates to electronic equipment and a computer readable storage medium. Through the invention, anti-decoding protection of peripheral memory data of a main control chip of the rewriting equipment is realized, the data security performance of the chip rewriting equipment is enhanced, and the invention is easy and convenient to implement and high in usability.
