A Secure and Efficient Access Control Mechanism for Network Slice Resources in Distributed Environment

In order to solve the problem of low security in transactions between multi service providers and multi bottom network providers, this paper proposes a secure and efficient network slice resource access control mechanism in a distributed environment. First, a secure and efficient network slice resource access control architecture in distributed environment is designed. The framework consists of multiple domains. The roles of each domain include multiple service providers, multiple underlying network providers, authentication servers, and resource use license servers. The overall mechanism of secure and efficient network slice resource access control in a distributed environment includes six steps: the service provider applies for identity authentication to the authentication server, the service provider applies for resources to the resource use license server, the resource use license server returns the list of underlying network providers to the service provider, the underlying network provider allocates resources to the service provider, the service provider applies for resources from a resource use license server outside the domain, and the resource use license server outside the domain returns a remote list of underlying network providers to the service provider. Finally, the mechanism in this paper has good performance.
