Dynamic Migration Optimization Algorithm for Virtual Machine under Trusted Computing Environment
Ling Tang · 2018
For the load balancing of the whole cloud computing architecture, we need to use the virtual machine's dynamic online migration technology. Based on TCCP model, this article improves the trusted third-party coordinator, and migrates partial management of TC to node TN to prevent the TC leakage which may cause the security of the whole model to be destroyed. At the same time, to ensure the integrity of the online migration, the trusted computing module provides a complete trust measure, stores the measurement value, and constructs a complete trusted chain, providing a platform to guarantee the remote verification of the migration. Finally, through the integrity measurement and verification function provided by TPM, measurement and validation are performed before the virtual machine starts migration, to ensure the integrity of the migration.
