VERFAHREN ZUM SCHUTZ GEGEN MANIPULATIONEN IN EINEM STEUERGERÄT FÜR EINE KFZ-KOMPONENTE UND STEUERGERÄT

摘要

The control system (1) consists of a microcomputer (muC) with a first circuit module consisting of a OTP (One-Time Programmable) module (11) with microcomputer (muC-ID) a Flash-ID region and an E2PROM-ID region and a master code (MC) region. The master code is transmitted to memory components (2,3) with OTP regions (21,31) with identity circuits (ID) and sub-code (SC) regions.
