| Summary: | The chip emulator is an effective debugging tool in the embedded software development, and many existing chip emulators lack the protection of the software program during the debugging process. This paper proposes a solution to control the access rights of software programs during the debugging phase. The solution mainly includes three steps: firstly, the program access rights is generated in the form of an encrypted configuration file, then the program data is encrypted, and finally the encrypted configuration file and the encrypted program data are downloaded to the chip emulator. The solution realizes flexible configuration of program access rights and adopts encrypted files to prevent unauthorized tampering of configuration rights and program data, and increases the security of debugging.
