Static measurement method of active immune trusted computing platform for blockchain master node

Abstract

The invention discloses a static measurement method of an active immune trusted computing platform for a blockchain master node, the trusted computing platform comprises a computing component and a protection component which are parallel, the computing component is used for completing computing tasks such as blockchain consensus, blockchain communication and blockchain transaction, and the protection component is used for performing active measurement and active control on the computing component according to the dynamic autonomous credible strategy through an active immune chip; the static measurement method comprises the steps that after a trusted computing platform is powered on, an active immune chip in a protection component is started before a block chain special CPU and hardware ina computing component, the protection component measures the starting process of the computing component step by step through an active immune chip agent with the active immune chip as the root of trust until the trust chain of the computing component is established. According to the method, the active immune chip serves as a source point of active measurement and active control, a safe and credible trust chain is constructed for the computing component, and the safety performance of the computing component can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of trusted computing, in particular to a static measurement method for an active immune trusted computing platform oriented to a block chain master node. Background technique [0002] Blockchain has become the focus of domestic academic and industrial circles. my country's blockchain technology and industrialization are advancing in an all-round way, and a large number of technological and industrialization achievements have been produced. However, the current research and industrialization results are mainly oriented to the application of blockchain technology, and the security of blockchain itself is less considered. However, the current cyberspace is extremely fragile, and various cyber attacks emerge in endlessly and become increasingly rampant. The root cause is that the problem is not solved from the real cause of network security risks, and the passive defense methods of "blocking and killing" repre...

However, TPM is essentially just a passively mounted external device on the computer. It will only function when it is called by the host program. Static measurement does not implement policy-based dynamic measurement when the computer is running, so the trusted computing architecture of TCG is basically difficult to resist when hackers use computer system logic flaws to attack. For example, Windows 10 fully realizes the trusted computing architecture of TCG. Computing architecture, but failed to prevent Wannacry ransomware attack
