Abstract


Grid users tend to applications and data into its custody beyond the control computing environment be trusted computing platform user application and data security threat. How to build a safe and reliable for the user job execution environment and protect the user's job security is very critical issue. Existing grid security infrastructure , mainly through authentication and authorization mechanisms to build trust in grid environment system, and insufficient to meet the security requirements. Grid-based Virtual Machine credible deployment of an effective solution to these security issues , in succession grid security infrastructure based on the introduction of virtualization and trusted computing technology to enhance the safety of the grid system . By signing and verification of identity certificate resource node platform , enhance trust system Grid Virtual Organization 's credibility ; in a grid environment to a virtual machine for the scheduling unit deployment can be customized for the user , controllable and reliable remote job execution environment, through the remote attestation mechanism validates resource nodes on virtual machines and virtual machine monitors the integrity of the boot file to determine the credibility of the job execution environment . User jobs effectively in the life cycle management and security , job transfer and storage is encrypted , virtual machine isolation to ensure that different users operating independently of each other , based on virtual machine monitor memory isolation mechanism to ensure execution of the job not to be malicious intrusion. Testing and analysis show that based on trusted computing and virtualization grid security architecture for the user to build a safe and reliable job execution environment . Trusted deploy virtual machines deployment requires 19 seconds compared to traditional overhead , where 14 seconds for the virtual machine image file integrity measurement and verification , 5 seconds for job execution environment credible evidence and credible mechanism to introduce and did not increase too much overhead.
