SECURITY DEVICE FOR SIMULATION SYSTEM, ITS METHOD, AND ITS PROGRAM

摘要

PROBLEM TO BE SOLVED: To prevent the leak of arithmetic models 19-21 to a component maker when transmitting a control block data file 15 to the component maker relative to a system executing the simulation of a control device 15' based on the file 15 by providing input parts 16'-18' of the actual control device 15', the input models 16-18 corresponding to the arithmetic parts 19'-21' and an output part 22', and the control block data file 15 having a display 3 displaying the arithmetic models 19-21 and the output model 22.

SOLUTION: This security device is so formed that, when transmitting the control block data file 15, the arithmetic models 19-21 to be kept secrete are displayed on a display 9 of a computer 7 in the component maker side in masked states.
