Problems solved by technology

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

Embodiment 1

[0049] A static measurement method for an active immune trusted computing platform oriented to a block chain master node provided by the present invention will be described in detail below.

[0050] A static measurement method for an active immune trusted computing platform oriented to blockchain master nodes, the trusted computing platform in this embodiment is such as figure 1 As shown, it may include: parallel computing components and protection components, the computing components are used to complete computing tasks such as blockchain consensus, blockchain communication, and blockchain transactions, and the protection components are used to pass active immune chips. The information strategy actively measures and controls the computing components; there is a security isolation mechanism between the computing components and the protection components, and they interact through dedicated access channels;

[0051] Static measures include:

[0052] After the trusted computing ...

Embodiment 2

[0058] The process of the protection component measuring the corresponding startup process of the computing component through each measurement agent in the active immune chip agent is described in detail below.

[0059] Such as figure 2 As shown, the protection component measures the corresponding startup process of the computing component through the active immune chip, the system boot verification measurement agent, the system kernel measurement agent and the application startup measurement agent in the active immune chip agent, which may include the following steps:

[0060] S1.1. After the active immune chip is started and before the blockchain-specific CPU and hardware of the computing component are started, the active immune chip measures the blockchain-specific firmware in the computing component. If the measurement result of the blockchain-specific firmware is untrustworthy, the protection component controls the computing component according to the dynamic autonomous ...

Embodiment 3

[0076] The process of measuring the memory of the current computing component at each stage after the measurement process of the blockchain-specific firmware is described in detail below.

[0077] Such as image 3 As shown, the protection component measures the corresponding startup process of the computing component through the active immune chip, the system boot verification measurement agent, the system kernel measurement agent and the application startup measurement agent in the active immune chip agent, including:

[0078]S2.1. After the active immune chip is started and before the blockchain-specific CPU and hardware of the computing component are started, the active immune chip measures the blockchain-specific firmware in the computing component. If the measurement result of the blockchain-specific firmware is untrustworthy, the protection component controls the computing component according to the dynamic autonomous trusted strategy;

[0079] S2.2. If the measurement ...

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...
