Abstract

The invention discloses an information integrity measurement verification method and system for a satellite-borne computing system. The method comprises the following steps: S1, establishing a trust chain in a whole starting sequence; taking the integrity trust module as a starting point, carrying out integrity measurement and local verification on the next object in the starting sequence on the premise of trusting the current object, considering that the next object is credible after the local verification is passed, transferring the control right to the next object, and sequentially pushingbackwards until the object in the whole starting sequence completes the local verification; S2, in the running process of the system, conducting integrity measurement and local verification on the data in the memory; and when the ground system sends a task to the satellite-borne computing system, carrying out data transmission after remote verification is passed. Safety measures are taken from thebottom layers of hardware and software of the satellite-borne computing system, measurement and verification of the system and key applications are increased, tampering attacks and the like can be better resisted, and the integrity and authenticity of platform codes and data can be verified.

Description

technical field [0001] The invention relates to the field of information security protection, in particular to a method for measuring and verifying information integrity of a spaceborne computing system and the spaceborne computing system. Background technique [0002] As an important infrastructure of national informatization, the satellite Internet network is the only way for my country's information network to achieve global coverage of information, broadband transmission, military-civilian integration, and free interconnection. Different from the existing satellite system, the satellite Internet is essentially a complex system that integrates the sky and the earth and "information + network", which collects and processes various data and information. The integrated application of heterogeneous satellite-ground networks in the future will introduce a series of information security risks. As a distribution center for a large amount of important information data, the satell...
