在当前的云中，在物理主机之间移动VM的VM迁移是不可或缺的。对于云提供商，在关闭物理主机进行维护之前，使用迁移将VM临时保存到其他物理主机。对于云用户，迁移用于将VM移动到地理上离最终用户较近的位置。这些VM迁移可以非常容易地执行，并且仅受VM管理员合同范围的限制。然而，问题出在VM中数据的权限上。近年来，随着物联网的广泛使用，各种类型的数据可以通过Web服务存储在云的VM中。物联网设备收集的海量数据需要密切关注管理，因为它可能与个人信息密切相关。然而，在VM迁移过程中，没有检查VM中的数据权限的机制，而且人们担心可能会发生不适当的数据移动。这包括不适当数据的意外危险移动，这可能是恶意数据。因此，我们提出了一种机制，以确保在VM迁移过程中遵守数据所有者授予的条件、国家法规和组织法规。通过在区块链中构建所提出的机制，我们可以防止恶意篡改，从而实现稳健的VM迁移控制。
In the current cloud, VM migration that moves VMs between physical host machines is indispensable. For cloud providers, before shutting down the physical host machines for maintenance, migration is used to temporarily save VMs to other physical host machine. For the cloud user, migration is used to move a VM to a location which is geographically close to the end user. These VM migrations can be performed very easily and are only limited by the scope of the VM administrator’s contract. However, the problem lies on the permission of the data in VM. In recent years, with the widespread use of IoT, various types of data can be stored in cloud’s VMs through web services. The huge amount of data collected by IoT devices requires close attention to manage because it could be very closely related to the information of an individual. However, there is no mechanism for checking data permission in VM during VM migration, and there is concern that inappropriate data movement may occur. This includes the unintended risky movement of inappropriate data which could be malicious data. Therefore, we proposed a mechanism to ensure compliance with the conditions granted by the data owner, the country regulations, and the organization regulations during VM migration. By constructing the proposed mechanism in blockchain, we can prevent malicious tampering and thus enable robust VM migration control.
