The invention provides a malicious encrypted traffic detection method and device. The method comprises the following steps: building an encrypted graph through mining the incidence relation between encryption sessions in encrypted traffic, and converting single-stream isolation analysis into multi-stream collaborative analysis. Meanwhile, two types of attributes describing the encrypted malicious traffic are provided, one is credibility of evaluation based on handshake information, and the other is stationarity of evaluation based on a TLS record length sequence, and a credibility value and a stationarity value of an encrypted session to be evaluated are comprehensively analyzed and calculated through a graph attention network. The above values are input into a pre-trained feedforward neural network to obtain a maliciousness score so as to identify the encrypted malicious traffic. According to the invention, through mining the relationship between encrypted sessions, the detection of malicious encrypted traffic is more accurate, and the robustness is higher.

The invention discloses a method for preparing polyurethane rubber granule mixture for pavement self-stress icebreaking, and relates to rubber mixture. The method comprises the steps of firstly, mixing various grain sizes of gravels and rubber particles for 60s at room temperature, obtaining gravel and rubber particle mixture, adding bi-component polyurethane glue which is modulated by a component A and a component B mixed for 120s at room temperature, mixing for 120s at room temperature, obtaining mixture of the gravel and rubber particles and the polyurethane glue; adding mineral powder to mix for 60s at room temperature, and preparing the polyurethane rubber granule mixture for pavement self-stress icebreaking. The mixed pavement material generates large compressive deformation in use, resulting in that the tensile stress and the shear stress inside an ice layer are obviously increased, so that the ice layer cracks. The ice layer is damaged under reciprocal action of vehicle tires, so as to overcome the problem that accumulated snow and frozen ice on the pavement cannot be effectively solved in the pavement paving material of inhibiting congelation in the prior art and the defects of poor pavement performance, low durability and non-environmental performance.

The invention discloses a hub motor and a suspension using the hub motor. The hub motor and the suspension using the hub motor comprise a hub motor suspension main body, the hub, a motor box, the suspension and a refrigeration device, wherein the periphery of the hub motor suspension main body is fixedly connected with the hub, the peripheral outer wall of the hub is connected to the peripheral outer wall of the hub motor suspension main body, the motor box is fixedly connected to the inner side of the middle of the hub, the peripheral outer wall of the motor box is connected with the inner side inner wall of the middle of the hub, and the middle of one end of the motor box is in lap joint with the suspension. According to the suspension, through a damping mechanism formed by a damping strut and a damping spring, the stability effect of the suspension itself can be well improved; the refrigeration device can ensure stable operation of a motor in the motor box, and a certain protectionand prevention effect on the motor is achieved; and for the hub, when a tire is installed, the contact area between a tire mounting groove and the tire can be effectively expanded through a limiting ring on the inner side of the hub, the firmness degree of the joint between the tire and the tire mounting groove is improved, and a wide development prospect in the future is achieved.

The invention provides a solid-liquid two-phase molar concentration detection system and method, comprising a solid-liquid two-phase molar concentration detection system, the system includes a rotating and heating device, a connecting device, a cooling metering device, and a control system. The rotation and heating device is mainly used for heating solid waste samples. Under the centrifugal force generated by the rotation, the heating efficiency is higher and the liquid is fully evaporated. The cooling metering device is used to cool the evaporated gas into a liquid, measure its volume at the same time, and detect the air humidity to judge whether the water has evaporated completely; the connecting device is used to guide the gas and prevent backflow; the control system is mainly used For the control of sensors, heaters, stepper motors and other equipment. Based on the principle of gravity method and combined with sensor detection, computer control and other measurement and control technologies, the present invention establishes an automatic detection method for solid-liquid two-phase molar concentration, which has the characteristics of accurate detection effect, stable process, simple operation and the like.

The present invention provides a method and device for detecting malicious encrypted traffic. The method constructs an encrypted graph by mining the correlation between encrypted sessions in the encrypted traffic, and converts single-stream isolated analysis to multi-stream collaborative analysis. At the same time, two types of attributes are proposed to describe the encrypted malicious traffic, one is the credibility of the evaluation based on the handshake information, and the other is the stationarity of the evaluation based on the TLS record length sequence. Confidence value and stationarity value, and input the pre-trained feed-forward neural network to get malicious score to identify encrypted malicious traffic. The invention detects the malicious encrypted traffic more accurately and has higher robustness by mining the relationship between encrypted sessions.
