This paper sums up four security factors after analyzing co-residency threats caused by the special multitenant environment in the cloud. To secure the factors, a multiway dynamic trust chain transfer model was proposed on the basis of a measurement interactive virtual machine and current behavior to protect the integrity of the system. A trust chain construction module is designed in a virtual machine monitor. Through dynamic monitoring, it achieves the purpose of transferring integrity between virtual machine. A cloud system with a trust authentication function is implemented on the basis of the model, and its practicability is shown.
