The invention discloses a method for analyzing the safety defect of a network protocol, and relates to the field of safety software engineering. The method comprises the following steps of: analyzing and summarizing the network protocol, and extracting resources, behaviors and harms of the protocol to model the network protocol so as to form an attack rule graph; analyzing all combinations of nodes and parameters in the attack rule graph according to the attack rule graph, and finding out at least one potential attack model; improving a rule knowledge library by using a reasoning mode; and formalizing the attack model in the improved rule knowledge library to establish an alleviation scheme corresponding to the attack model, and finally generating a network protocol attack analysis report. The method provided by the invention is more intelligent; on the protocol modeling aspect, the protocol can be better understood by a computer so as to extract effective information; and the background reasoning is performed based on the rule knowledge library, so that the shortcoming of the prior art is overcome, and the demand in actual application can be met.

The invention provides a raw gemstone machining method. The raw gemstone machining method comprises the steps that a plurality of image collecting devices and a host machine are provided, wherein the image collecting devices obtain gemstone image information and transferring the gemstone image information to the host machine, and the host machine judges whether internal jade has been exposed out of the two sides of gemstone already or not according to the gemstone image information and moves two cutting machines to the two sides of the jade when it is judged that the jade is not exposed out of the two sides of the gemstone; the cutting machines are started until cutting at the time is completed; a first two-claw air cylinder on a first grabbing mechanism grabs the gemstone, a first mechanical arm drives the first two-claw air cylinder to rotate, and the gemstone is placed on a first lifting table after the angle of the gemstone is adjusted; and a second two-claw air cylinder on a second grabbing mechanism grabs the gemstone from a conveying belt, and places the gemstone on a second bearing plate of a second lifting table, the gemstone is fixed to the second bearing plate through two side fixing mechanisms, and the gemstone is polished through a polishing mechanism. The cutting devices and the polishing device are used in cooperation, and therefore maximized removal of gemstone skin and shell is carried out on the premise that the integrity of the interior jade is guaranteed.
