ABSTRACT

The chip emulator is implemented by emulating the chip function and can be used for debugging of embedded software programs. On real chips, especially those used in the security field, for security reasons, in order to prevent illegal reading or tampering, it need to protect programs, configuration information and other data which are sensitive. Similarly, when using the chip emulator for program debugging, in particular, the program data and related configuration information that is provided to the user for security function calculation still needs to consider its security and security protection measures. This paper provides a data protection measure, which mainly includes data access right configuration function, data secure download function. Through the configuration of reading, writing and debugging right to protected data, and encrypt download of data, the program can be safely debugged to achieve data protection.
