Research On Secure Service Mechanism In Cloud Computing

With the rapid development of technology and application about cloud comput-ing, the security problem is becoming more and more important. It has important theoretical and realistic significance to comprehensive research and analysis various security problems that cloud computing facing.In this thesis, we focus on three types secure service mechanisms:secure store service, secure authentication service and secure access service, specific include:1. Secure store service in cloud computing:In the environment of cloud storage network, a new Secure Store Protocol named SSP is proposed. This protocol can not only store the data safely, but also can support data integrity verification service;2. Secure authentication service in cloud computing:In the model of Software as a Service (SaaS), presents a Secure Authentication Signature (SAS) to deal with authentication issues in SaaS and keep the interests and rights of all participants in safety;3. Secure access service in cloud computing:Aim at abundant and flexible of cloud services, designs a Secure Access Policy (SAP) supporting variable decisions that can provide secure access control for cloud services as required.
