Design and Implementation of Trust-based Access Control Model for Cloud Computing

In recent years, cloud services are frequently attacked. Cloud computing access control has attracted high attention in recent research field. The dynamic nature of cloud computing users and resource allocation determine that traditional access control is no longer applicable. This paper introduces the concept of trust in role-based access control, and designs a Trust-based Access Control Model. The introduction of trust is contribute to identify malicious users. Dynamic access control is well adapted to cloud computing. Through the above mechanisms this model guarantees the security of cloud computing and data.
