Problems solved by technology

Compared with the traditional distributed storage, the most special feature of satellite data distributed virtual storage is that a virtualization layer is added between the storage device and the application layer, while the existing security protection technologies for satellite data storage mainly adopt application Layer data encryption and authentication mechanisms, such methods do not take into account the security protection issues of the virtualization layer, and cannot guarantee the confidentiality, integrity, and credibility of the satellite data distributed virtualization storage system, and are especially vulnerable to APT attacks and 0Day Malicious stealing, illegal tampering and encrypted extortion of satellite data by new cyber attacks such as

Embodiment 1

[0063] In consideration of the confidentiality, integrity and credibility of distributed virtualized storage of satellite data, the embodiment of the present invention discloses a security protection system for distributed virtualized storage of satellite data, including: a platform trusted measurement module, Data encryption protection module, security monitoring and auditing module, trusted management server, key management server and log audit server. Among them, the platform trust measurement module, data encryption protection module and security monitoring and auditing module are set on the host computer side; the trusted management server, key management server and log auditing server are set on the security management server side.

[0064] Preferably, the platform trusted measurement module and the corresponding trusted management server are used for trusted measurement of the satellite data distributed virtual storage; the data encryption protection module and the corre...

Embodiment 2

[0073] refer to figure 1 , is a schematic structural diagram of a security protection system for distributed virtualized storage of satellite data provided by an embodiment of the present invention. In the invention, the security protection system for distributed virtualized storage of satellite data includes a distributed virtualized storage node 100 and a security management server 200 .

[0074] Specifically, the distributed virtualized storage node 100 specifically includes: a platform trust measurement module 21 for 20-layer security protection of the host operating system, a data encryption protection module 22 and a security monitoring and auditing module 23, and a virtual machine 30A vTCM metrics module 32A, vTCM reporting module 33A and audit proxy module 34A for layer security protection.

[0075] Wherein, the platform trust measurement module 21 includes a TCM measurement submodule 211 , a TCM report submodule 212 and a vTCM management submodule 213 . Since the ro...

Embodiment 3

[0086] refer to figure 2 , is a flow chart of a security protection method for distributed virtual storage of satellite data provided by an embodiment of the present invention. The security protection method for distributed virtual storage of satellite data is specifically a platform credibility measurement method, including the following steps:

[0087] Step S11, the TCM measurement submodule 211 calls the physical TCM11 to perform trusted measurement on the host operating system 20 and each application program, and sends the measurement result to the TCM report submodule 212, and the TCM report submodule 212 passes the measurement result through the SSL secure channel Send to trusted management server 201;

[0088] Step S12, the vTCM measurement module 32A invokes the vTCM instance generated by the vTCM management sub-module 213 to measure the credibility of the guest operating system 31A and each application program, and saves the measurement results to the vTCM report mod...

Abstract

The invention discloses a safety protection system and method for distributed virtualized storage of satellite data. The system includes: a platform trusted measurement module, a data encryption protection module, a safety monitoring and auditing module, a trusted management server, and a key management server and log audit server; the platform trusted measurement module and the corresponding trusted management server are used for trusted measurement of satellite data distributed virtual storage; the data encryption protection module and the corresponding key management server are used for satellite data The distributed virtualized storage performs data encryption; the security monitoring and auditing module and the corresponding log auditing server are used for security monitoring and auditing of the distributed virtualized storage of satellite data. The present invention constructs an integrated security protection mechanism of platform credibility measurement, data encryption protection, security monitoring and auditing, especially capable of defending against new types of network attack threats such as 0-Day attacks and APT attacks, and ensuring the security of satellite data.

Description

technical field [0001] The invention relates to the technical field of security protection for satellite data storage, in particular to a security protection system and method for distributed virtual storage of satellite data. Background technique [0002] With the continuous deepening and development of satellite applications in my country, a large amount of data has been accumulated in various related fields and industries, and the application requirements for large-scale satellite data sharing and integration and analysis and mining are also emerging. [0003] At present, the storage method of satellite data is transforming from traditional centralized unified storage to distributed virtualized storage. Compared with the traditional distributed storage, the most special feature of satellite data distributed virtual storage is that a virtualization layer is added between the storage device and the application layer, while the existing security protection technologies for s...
