Resource Security Management Mechanism Based on Dynamic Key and Blockchain in Network Slicing Environment

In order to solve the problem of economic loss caused by malicious use of underlying network resources by network attackers, this paper proposes a resource security management mechanism based on dynamic key and blockchain in the network slicing environment. First, a resource security management architecture based on dynamic key and blockchain in the network slicing environment is designed. The architecture includes two modules: the bottom network provider and the service provider. Each module consists of three sub modules: the certification center, the resource management center, and the resource settlement center. The overall mechanism of resource security management based on dynamic key and blockchain in the network slicing environment includes three steps: the service provider obtains the permission to apply for resources, the service provider applies for and obtains resources, and the underlying network provider completes the resource cost settlement. Through the analysis of resource security performance from three aspects of preventing man in the middle attack, preventing data tampering, and data leakage, we can see that the resource security management mechanism proposed in this paper can better solve the problem of economic loss caused by malicious use of underlying network resources by network attackers.
