This paper constructs RIP attack message by Python program in the experimental environment, and sends the attack mes-sage to the target router for routing deception, which makes the attacked router learn the wrong routing information, and then makesthe attacked router unable to realize the normal routing forwarding function. On this basis, we write packet sniffer program in Py-thon, analyze the attack message sent by the attacker, study its attack means and methods, and then take corresponding security mea-sures to enhance the security of RIP routing protocol.

Since the traditional battery power supply mode cannot meet the energy consumption requirements of WSN (Wireless Sen-sor Network), a photovoltaic power generation system based on WSN node energy supplement is designed. According to the infor-mation of illumination intensity collected by four regions photoelectric sensors, STM32minimum system drives and controls thehorizontal and vertical steering gear, which makes solar panels obtain maximum illumination intensity in time. When the lithium bat-tery and capacitor hybrid energy storage scheme is adopted, the experimental results indicate that the charging current of0.1A can beprovided for the lithium battery under the test conditions. After continuous charging for half an hour, the voltage of the lithium bat-tery can be increased by8.47%, which can prolong the life of the wireless sensor node.

In recent years, with the development of information technology, mobile augmented reality, as an emerging way of experience,has been widely applied in the current teaching resource design process. In the field of educational game development, there are many augmented reality educational games that integrate mobile augmented reality technology with the characteristics and advantages of educational games. Based on mobile augmented reality technology, this study develops a natural popular science game.By creating a relatively real and interactive natural science learning environment, many learning materials that were once difficult to appear can now appear in front of learners in the form of virtual images. It can cultivate learners' scientific inquiry ability, shorten and improve urban and rural students' ecological protection knowledge level, and shape the correct emotional attitude and values towards nature, which provides a train of thought for the integration of urban and rural education.

The education and teaching reforms in our country's institutions of higher learning put forward the requirement of "highlevel,innovative and challenging" for curriculum teaching. For the network security and law enforcement majors, in order to achieve the goal of the golden course of the Python Programming Language course, this article fully analyzes the position and role of the course in the professional curriculum system based on the training goals and actual development needs of professional talents. From the perspective of the professional curriculum system, the curriculum content is divided into structures, and the content is designed according to the gradual level. The curriculum content design selection is close to practical application and plays a key role in supporting the core curriculum of subsequent professional courses. Through the reform and design of the curriculum content, the enthusiasm and effect of the course learning of Python Programming Language are improved, and the degree of adhesion between the courses in the curriculum system in the professional training process is increased, which is of great significance to the talent training role of the entire curriculum system.

C Program Design occupies a significant position in the course of electronic information major, but there are still some defects in daily teaching. Based on the CDIO concept of International Engineering Education, combining with the training concept of EIP outstanding engineer talents, a kind of student-friendly teaching way is introduced in this paper, which aims at cultivating senior engineering talents. This way is similar to the game tasks, with chapters as a unit to set up multiple hierarchical links. It is beneficial to improve spirally knowledge, ability and quality for students.

The network traffic detection system based on machine learning is a hot research direction in the field of network security at this stage, but at the same time, the network traffic detection system has been greatly challenged. The generation of attack samples reduces the detection performance of the detection system for malicious traffic. This article uses the generative adversarial network to generate adversarial samples, by adding noise interference to the original malicious traffic, so that non-directional disturbances that do not affect the characteristics of the original traffic are added to the attack characteristics to realize the judgment of the jamming detection model, thereby avoiding the characteristics detection and reducing the accuracy of traffic detection by 83.4%. It provides a richer training sample for the intrusion detection model to improve its robustness.

In response to the Ministry of Education's 2021 work point of“accelerating the revitalization of higher education and enhancing the service capacity of promoting high-quality development in central and western China”, graduates in recent three years of Computer Science and Technology of Liupanshui Normal University are surveyed.

Stream processing frameworks are used in many Internet of Vehicles projects. When the producer pushes messages to the proxy server, due to data throughput problems, the server may be down, and the system needs to be restarted to restore to the state before the downtime. However, some data may be lost at this time. In response to this problem, key task hot backups can be used to help record the read and write status, which can better ensure data consistency, and improve system fault tolerance.
