This study aims to speed up the progress of scientific research projects in colleges and universities, continuously improve the innovation ability of scientific research teams in colleges and universities, and optimize the current management methods of performance appraisal of college innovation ability. Firstly, the needs of the innovation performance evaluation system are analyzed, and the corresponding innovation performance evaluation index system of scientific research team is constructed. Secondly, the Internet of Things (IoT) combines the Field Programmable Gate Array (FPGA) to build an innovation capability performance appraisal management terminal. Thirdly, the lightweight deep network has been built into the innovation ability performance assessment management network of university scientific research teams, which relates to the innovation performance assessment index system of scientific research teams. Finally, the system performance is tested. The results show that the proposed method has different degrees of compression for MobileNet, which can significantly reduce the network computation and retain the original recognition ability. Models whose Floating-Point Operations (FLOPs) are reduced by 70% to 90% have 3.6 to 14.3 times fewer parameters. Under different pruning rates, the proposed model has higher model compression rate and recognition accuracy than other models. The results also show that the output of the results is closely related to the interests of the research team. The academic influence score of Team 1 is 0.17, which is the highest among the six groups in this experimental study, indicating that Team 1 has the most significant academic influence. These results provide certain data support and method reference for evaluating the innovation ability of scientific research teams in colleges and universities and contribute to the comprehensive development of efficient scientific research teams.

“…Say it is ancient; it is because humans used simple cryptography thousands of years ago, in order to preserve and transmit classi ed political and military information. But the cryptographic ideas and technologies of this period were not so much a science as an art [10] because at this time, when cryptographers design and analyze cryptographic algorithms, they mainly rely on intuition and manual calculations, and there is no strict theory as the basis.…”

In order to solve the practical problem that the security of computer network information cannot be guaranteed, which seriously affects the network performance, the author proposes a public key data encryption system based on PKI. The system proposed by the author is based on the public key cryptographic algorithm RSA, including implementation of data encryption and digital signature and key distribution, an improved RSA algorithm is proposed for the slow speed of RSA. The result obtained is as follows: after reasonable selection of parameters and the use of optimized algorithms (also known as combined algorithms), the RSA algorithm is about 1.0% to 2% more efficient than the traditional algorithm, to a certain extent, the operation efficiency of the RSA algorithm is improved, and the purpose of improving the RSA algorithm is achieved. It is proved that the public key data encryption system is of great significance for modern computer network information encryption and maintaining a green and secure network environment.

With the development of technology and the diversification of information acquisition methods, video has become an important component of our daily life and work, and the security of video information is of increasing concern. In this work, a general video encryption algorithm is proposed and implemented. The algorithm extracts a video file frame by frame to obtain video frames and encrypts the video by encrypting its frames. The bilinear interpolation method is used to reduce the size of the video frames, and then one of the four fractional order chaotic systems and one of three scrambling methods are selected to scramble and diffuse the video frames. This work conducted in-depth feasibility testing on the encryption and decryption process, analyzed the resistance to statistical attacks, and completed tests on the histogram, correlation of adjacent pixels, and information entropy, as well as sensitivity analysis and noise resistance analysis. Moreover, the ability of encryption and restoration were compared with other methods. In addition, the performance comparison of three scrambling methods was also conducted. The encryption effect of these methods is not very different, but the restoration ability of the pixel scrambling is not as good as the other two methods. The experimental results show that this algorithm has better security and encryption efficiency.
