A Cloud Service Attribute Access Control Model Based on Trust Evaluation

Aimed at the problems of security access control cloud services in cloud computing, a cloud service attribute access control model based on trust evaluation was put forward. Combined with access control framework based on attribute, a trust evaluation method based on service quality indicators is proposed. Direct trust, indirect trust and comprehensive trust are utilized to evaluate the credibility of cloud resource.The simulation results show that the model can correctly and effectively prevent cloud users access to malicious and untrusted services. The security of cloud service access is improved.
