Abstract: This paper introduces a new kind of cryptogram lock. To develop a better characteristic of guard against theft, one must rightly use fixed first code with authentication code (decided by your algorithm of each time) to open door. The paper illuminates its basic physical theory by hardware circuit and the control theory by frame figure , puts forward a secure cryptography that has not been found in this field before .
