Research on opening the electronic optical fiber seal without being detected

Takes a definite orders correspondence electronic optical fiber seal as the object, explores the feasibility and the validity of the software method of attacking the seals without being detected. The experimental results show that: (1)In the case of knowing the control key but unknowing the serial port communication protocol, the serial port communication protocol can be obtained by the software attack technology ; (2) In the case of knowing the serial port communication protocol but unknowing the control key, when the control key figure is low and simple, it can be obtained by the software attack technology ; But along with the key figure and complex degree's increase, unlocking time will increase in the exponential order. In the case of knowing nothing about the key and the communication protocol, brute-force attack does not have the feasibility.
