Embodiment Construction

[0052] In order to make the purpose, advantages and adopted technical solutions of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0053] The present invention proposes an overall dynamic migration method of a virtual root of trust vTPCM instance of a virtual machine VM, such as figure 1 Shown is a structural block diagram of the migration system when the migration of the virtual root of trust vTPCM instance of the virtual machine VM does not occur, and the control node is used to send the creation, migration and deletion commands of the virtual root of trust vTPCM instance of the virtual machine VM to the computing node.

[0054] figure 2 It is a block diagram of the migration system when the overall dynamic migration of the virtual root of trust vTPCM instance occurs. The control node and the source platform A...

Abstract

The invention discloses an overall dynamic migration method for a virtual trusted root vTPCM instance of a virtual machine VM. The invention belongs to the technical field of trusted security migration of system operation state information. The method is characterized in that the method is characterized by comprising, this is a source platform that is determined as an emigration node on the basisof a request from a control node administrator to compute a node. The invention discloses a target platform of an immigration node and a vTPCM instance overall dynamic migration method realized in a migration system of a control node based on a known trusted platform control module TPCM, the emigration party and the immigration party are jointly controlled by a respective trusted platform controlmodule TPCM and a control node CPU; symmetrical and asymmetric encryption algorithms are used; the hash algorithm and the image value forming method of the mkImage tool are realized by using a credible calculation method according to operation state data acquired by a controlled system in different states in the whole operation process as reference values. Compared with an existing vTPCM overall dynamic migration method, the method has the advantages of being safer, simpler, more convenient and higher in migration efficiency.

Description

technical field [0001] The invention relates to an overall dynamic migration method of a virtual root of trust vTPCM instance of a virtual machine VM, which belongs to the technical field of reliable and safe migration of system running state information. Background technique [0002] With the rapid development of computers and the Internet, people have higher and higher requirements for the security of application software on computers, and security issues have become increasingly prominent. In this context, trusted computing came into being, and Trusted Platform Module (Trusted Platform Module, TPM), Trusted Platform Control Module (Trusted Platform Control Module, TPCM) and Trusted Cryptography Module (Trusted Cryptography Module, TCM) It is the core component in the field of trusted computing. [0003] The trusted platform control module TPCM is a security chip integrated on the trusted platform independently developed by my country. It is the trusted root of the active...
