Abstract

See full text

A rewrite detection system, a rewrite detection device and an information processing device can detect unauthorized rewrite to a program or data stored in a storage unit of the information processing device. A rewrite detection device generates a random seed and transmits it to an ECU and a server device. The ECU calculates a hash value using a predetermined hash function on the basis of the received random seed and the storage content of the storage unit, and transmits the hash value to the rewrite detection device. The server device transmits an expectation in response to an inquiry from the rewrite detection device. The rewrite detection device determines whether unauthorized rewrite to a program or data in the ECU has been performed or not in accordance with whether the expectation received from the server device and the hash value received from the ECU coincide with each other or not.
