A check computation circuit executes a computation corresponding to a computation for generating confidential CRC data, with respect to confidential data read from a non-volatile device. A comparison circuit compares the result of the computation in the check computation circuit with confidential CRC data read from the non-volatile device. When the result of the comparison indicates a mismatch, i.e., an error is detected, an encryption circuit encrypts the confidential data and the confidential CRC data using a secret key registered in a secret key register, and outputs the encrypted confidential data and confidential CRC data to the outside of a semiconductor integrated circuit.
