Embodiment Construction

[0077] The technology of this patent needs to pay attention to the following matters during the specific implementation:

[0078] 1) An external trusted entity provides a trusted cloud manager to verify the networked operating system platform. TCC manages a directory locally, which stores the signed public key EK of the trusted physical node in the networked operating system PU N , public key TK PU N and the configuration list CL N In addition, it is also responsible for publishing its own signature public key EK through a secure channel. PU TCC , public key TK PU TCCand the expected TCC configuration list CL TCC .

[0079] 2) This patent also assumes that the following conditions are established:

[0080] a) The trustworthiness of external trusted entities does not need to be verified;

[0081] b) TCC's signed public key, public key and expected configuration list, physical node's signed public key and expected configuration list are published before the system run...

Abstract

The invention discloses a network-operating-system-oriented trusted virtual operating platform technology, which belongs to the technical field of computer infrastructure software. In the technology, trusted registration and starting mechanisms are designed for each node in a network operating system by setting a third-party trusted authentication mechanism which is a trusted cloud controller for main threats to the main service range and main operations of the network operating system in a typical novel network application mode; and after passing through an authentication protocol of the trusted cloud controller, the nodes can become trusted nodes to provide a trusted host operating environment for virtual machines, ensure that damages to the integrity and accuracy of the virtual machines can be detected in a starting process and interrupt the starting and registration processes of damaged machines. Moreover, corresponding trusted ensuring mechanisms are designed for the main operations of the virtual machines, namely starting and migration processes.
