Summary: | An image processing apparatus according to an embodiment has: a first pseudo random number generator configured to generate a pseudo random number and write the pseudo random number into a first memory; a processing circuit configured to read out the random number from the first memory, execute specific processing on the random number, and write a processing result of the specific processing into a second memory; a first signature generator configured to read out the processing result from the second memory, and generate a signature based on the processing result; and a first signature comparator configured to compare the signature generated by the first signature generator and a first expected value, the first expected value being an expected value of a signature based on the random number generated by the first pseudo random number generator and based on processing contents of the processing circuit. |
