Research on Information Security of IoT Nodes Based on Blockchain
We have conducted research and analysis on the information security issues of e-commerce IoT nodes in blockchain,including trusted computing and privacy protection.A malicious node detection trust model(BTW)was designed,which combines trusted computing and homomorphic encryption blockchain technology for frequent data exchange in blockchain networks to protect the security of e-commerce IoT node information and obtain an overall model for node information security.The experimental results show that the CPU performance of the BTW method is significantly better than that of traditional methods.Compared to traditional block-chain transaction processes,the trusted computing business process proposed in the study can shorten the business process by 50％-75％,and the overall effect of privacy node protection is better than traditional methods.A IoT node information security protection model that integrates malicious node detection,trusted computing,and homomorphic encryption blockchain can provide better security guarantees.
