Simulation of Complex Network Based on on-chain Data Security Access Control

Aiming at the problem of link data security, this project aims to improve the efficiency and security of link data access control, and studies the secure access control method of link data. On this basis, a decision tree data storage model for network chain is constructed by using distributed fusion technology. According to the characteristic components of the link data, the transmission rate, transmission round trip time and packet loss rate of the link data are calculated, and the packet loss smoother is used to process the link data, and the link data is adjusted according to the smoothness analysis result, so as to realize the secure access of the data. Experiments show that the control strategy proposed in this paper can effectively improve the control effect and security of the system.
