A Security SLA Negotiation Mechanism Oriented to Mimic Cloud

Mimic cloud systems can effectively defend against security threats such as vulnerabilities and backdoors in the cloud environment, and improve the security and reliability of cloud services. However, in view of the service quality and security requirements of different users, the mimic cloud system usually has a certain degree of blindness when selecting heterogeneous executors, and it is inevitable to measure the diversity of heterogeneous executors. Based on this, a security SLA negotiation mechanism for mimic cloud is proposed, which can provide a mapping from user needs to mimic cloud resource requirements. First, the cloud platform analyzes user needs from the formal SLA template, and screens out the executors that meet the user's service quality requirements; furthermore, the mimic cloud platform constructs a diversified system attribute matrix to measure the diversity of heterogeneous group of executors; finally, the analytic hierarchy process is used to select a set of optimal heterogeneous executors from the pareto optimal solution set that meets the needs of users to provide services for users.
