PROCEDURE OF MODIFICATION OF DATA IN PERMANENT STORAGE OF UNIT CONTROLLING ENGINE

摘要

engine manufacture. SUBSTANCE: invention can be used in unit controlling engine to detect illegal modification of data in permanent storage. Characteristic feature of invention lies in that message on legitimacy of conducted modification of data is entered in permanent storage when data are modified. In this case message on legitimacy of modification of data can include information on test sums of data put into sectors of permanent storage of unit controlling engine. This message can be encoded prior to recording in permanent storage. Objective of proposed procedure of modification of data in permanent storage of unit controlling automobile engine is formation of mechanism of early detection of illegal modification of data in permanent storage of control unit. EFFECT: early detection of illegal modification of data in permanent storage of control unit. 1 cl, 1 dwg
