With the continuous deepening of social informatization, the Internet of Things (IoT) devices are used in large quantities. Traditional centralized access control cannot meet the network access control requirements of large-scale IoT environments. Access control is one of the importation technology of information security. This paper establishes the dynamic game access control model which encourages interactive entities to rationally choose strategies expected by the system driven by its own benefits through the designed mechanism. Taking benefits as the driven force, the mechanism rewards the honest nodes and punishes and restrains the non-honest nodes, and then reaches the general state of equalization between entities which meets the goal. Finally, experiments prove that this method is effective in the open Internet of Things, which can greatly enhance the security of data access between IoT sensors, and can effectively protect the privacy of network entity data.

As an industry-specific dedicated communication network, electric power communication is gradually formed and developed with the development of power systems. It is mainly used to alleviate the lack of communication capabilities caused by the slow development of the public network and to fill the public network's inability to meet the special communications of some power departments. The contradiction of demand to ensure the normal and efficient operation of specialized electric power production. Nowadays, power communication security technology is becoming more and more important, and detecting the disconnection of communication cables is the main means to ensure smooth communication. This paper proposes a distributed monitoring system to detect the disconnection of communication cables. MSP430F149 and FPGA are used to form a high-speed variable sampling rate system to detect obstacles in communication cables. DTMF dial chip MT8888 and embedded modem chip MSM7512 are used to realize remote alarm and data exchange functions. The whole system is easy to control, flexible, and expandable. The experimental results show that this article has solved the problem of online monitoring of communication cables. The sustained and rapid growth of China's economy has provided a huge market space for the development of communication cable security technology. The strong temptation of the Chinese market has made the world focus on the Chinese market. The huge production capacity formed by China's cable security technology let the world admire. With the continuous expansion of China's power industry, data communication industry, urban rail transit industry, automobile industry, shipbuilding and other industries, the demand for wires and cables will also grow rapidly. In the future, there is still huge development potential for wire and cable protection.

In order to achieve the purpose of integrating VFW flexibly and improving its efficiency, application of virtual firewall (VFW) in computer network security has been explored. OpenStack-based cloud platform VFW system is analyzed with functional requirements and non-functional requirements, and the functional modules of the VFW are divided. Then, the design of VFW system architecture, application layer and functional modules is carried out. Based on the development of OpenStack cloud platform, the realization process of each functional module is elaborated, and finally, a novel queuing model is used to test the efficiency of the VFW system and the test results are analyzed. The theoretical packet loss rate of VFW system is higher than that of simulation experiment, and the error is larger when the number of VFW deployment is small. The average error between the theoretical and simulation results is 6%, and the final error after adjusting the algorithm is 4%. The optimal deployment scheme obtained by simulation experiment is highly consistent with the theoretical results. The model can successfully simulate the deployment of VFW and quickly get the optimal deployment scheme.

Colleges and universities are person-intensive places, and it is difficult for them to prevent and control the epidemic after students return to school. In the post-epidemic era, college students face many difficulties in health and safety. In view of the poor fire-fighting facilities, difficult evacuation and difficult temperature monitoring in and out of dormitories, this paper developed a digital alarm system in the post-epidemic era with college dormitory as the carrier. The system was divided into two parts: the master controller and the monitoring nodes. The monitoring nodes were installed in each dormitory room. The data was collected by temperature sensor and smoke sensor, and the data was transmitted to the upper computer by wireless module. According to the functional requirements of the digital alarm system, the upper computer interface had designed two modules: temperature anomaly alarm and fire alarm. The upper computer could display the data monitoring situation of each dormitory and realized digital alarm according to the data analysis results.

We present a giant chaotic network having the characteristics of a giant nonlinear chaotic dynamic system. Based on two space coupling Lorentz systems with different parameters, a hyper-chaotic energy source is used to drive each chaotic system in two-way. Which results in a parallel series network with two ways. Each node in two-way of network is a highly nonlinear dynamic system and has the chaotic characteristics, where each node of network is a chaotic system. Then, we define such network as a giant chaotic network or a giant nonlinear chaotic dynamic system. We find many hyper-chaotic states and their hyper-chaotic regions via a Lyapunov exponents diagram. We also give a bifurcation diagram to illustrate roughly dynamic behavior of the two coupling Lorentz system from a stable state to a single-periodic state, a multi-periodic state, a chaotic state and a hyper-chaotic state by shifting some parameter. And we discuss all kinds of state synchronization difference via the maximal LES. The network can be found to obtain a hyper-chaotic synchronization and all kinds of state synchronizations in all nodes in two-way. Our research result is of great significance to the research of artificial network, complex system and artificial intelligence.

Using the array signal reception theory, we analyzed the mathematical model of the proposed time-modulated rectangle array (TMRA). For practical applications, the uniform circular arrays (UCAs) used in orbital angular momentum (OAM) based multiple-input-multiple-output (MIMO) systems are replaced by the general uniform rectangle arrays (URAs). The employment of radio frequency (RF) switches at the bandlimited receiver significantly reduce the hardware overhead and avoid the unlimited spectrum expansion caused by switches. The detailed derivation of an example of 4 × 4 TMRA time-modulated sequence (TMS) is given in this letter. Our numerical results demonstrate that the TMRA receiver obtains better reception gain, bandwidth, and sidelobe control than a single UCA based OAM receiver.

In order to enhance the visualization of low-quality images and adapt to the practical work of public security picture detection and visual detection in haze weather, we integrate the currently widely applicable processing methods and adopt a new processing method. This method uses the quad-tree method to solve the problem of the selection defect of the priori atmospheric light value of the dark channel. Aiming at the interference effect between the wavelet frequency division reconstruction coefficients, the adaptive correlation method under the gradient is applied. For noise that gains along with wavelet coefficients, we gives a noise reduction method by compromises the threshold. The experimental results show that the hierarchical contrast of the image is fine, the color fidelity is fine, and the indicators are generally better than other algorithms.
