Security model and design of network communication system based on data encryption algorithm

Implementing cryptographic services based on network communication systems, improving data encryption algorithms, and providing basic support for secure communication technologies use homomorphic encryption to secure network communications systems data security in the process of communicating with cloud machine learning services; transplant cloud machine learning models into network communication systems, directly compute machine learning models based on network communication systems, and perform traffic intrusion detection. According to the software design and development process, the use case diagram has been used to analyse the requirements of the middleware system, and abstract the functional modules that the middleware system should have. Then, the overall structure of the middleware system is designed, the overall process of the system is determined, and each functional module is designed in detail, and then the interaction and dependencies between the modules are determined through the sequence diagram.
