Abstract: A method for diagnosing secure communication. Before performing a data transmission, a self-diagnosing mode is entered. Error checkpoints are checked to generate a diagnostic status. The diagnostic status is collected. An error handling mode is entered to determine whether an error exists in the diagnostic status. When there is an error, the error is shielded. The method for diagnosing secure communication solves the problem of image burn-in, and further reduces the use of non-volatile memory. Therefore, the size and function utility of the integrated circuit can be further reduced.
