Research on security defense based on randomization in cloud computing environment

Abstract

Cloud computing uses cloud resources to provide users with computing and storage services It has changed the processing mode of information resources for individuals and enterprises But The existing security reinforcement methods of cloud computing environment can not deal with external attacks caused by the singularity of cloud computing environment services and its own vulnerabilities This article starts from the cloud service itself the security threats of cloud computing platform are studied from three aspects: cloud service interface and network interface In order to deal with these security threats, the cloud service itself is analyzed and compared Randomization method of cloud service interface and network interface next. A randomization deployment model with multi-level, inter layer randomization awareness and distributed collaboration is proposed. The problem of randomization parameter awareness in model deployment is discussed the cooperation of the same layer services on different virtual machines The corresponding solutions are given. Finally, the security measures and limitations of the randomization method are discussed. Point out the future research direction.
