APPARATUS AND METHOD FOR GUARANTEEING INTEGRITY OF REAL-TIME VEHICLE DATA AND VEHICLE BLACK BOX SYSTEM USING THE SAME

A vehicle black box technique guarantees the integrity of vehicle data stored in a black box in real time by forming input data streams as block data and performing a signature using a signing key and nested hashing. Each vehicle black box includes a reliable unique signing key supporting a non-repudiation function. An error correction function is provided by a unique algorithm for generating integrity verification data even when an error occurs from the vehicle data.
