Detailed Description
It is not necessary for any particular embodiment of the invention to achieve all of the above advantages at the same time.
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment,
The present embodiment discloses a method for performing internet node authentication based on neighbor reliability, as shown in fig. 1, fig. 1 is a flowchart of a method for performing internet node authentication based on neighbor reliability provided in the present embodiment, where the method for performing internet node authentication based on neighbor reliability includes:
s101, determining a first internet node and a second internet node which are communicated in an internet system, and establishing an authentication connection between the first internet node and the second internet node;
s102, according to the first neighbor credibility certification of the first internet node and the second neighbor credibility certification of the second internet node, mutual authentication is conducted between the first internet node and the second internet node.
Optionally, in this embodiment, the internet system may be a big data system, and the internet system is composed of a plurality of internet nodes. For example, the internet system is a blockchain system, and the internet nodes therein are blockchain nodes. Specifically, the block chain system is, for example, a federation chain, a private chain, or a public chain; alternatively, in this embodiment, the block chain link points may be block chain light nodes and block chain full nodes. The block chain whole node is a node which possesses all transaction data of the whole network, and the block chain light node is a node which only possesses the transaction data related to the light node.
It should be noted that, in this embodiment, when a plurality of block chain nodes form a block chain system, the authentication system may be deployed only on the block chain node, where the authentication system includes an authentication kernel, and the first authentication system on the first internet node and the second authentication system on the internet node respectively authenticate each other between the first internet node and the second internet node according to a first neighbor reliability certificate in the first internet node and a second neighbor reliability certificate of the second internet node.
Here, it should be noted that, for the private chain, since the number of blockchain nodes is relatively small, for this reason, in order to ensure the safe operation of the blockchain system, the above authentication system may be deployed on all blockchain nodes. For another example, for a federation chain, the above-described authentication system may be deployed on all blockchain nodes with reference to a private chain. For example, for a private chain, since the number of blockchain nodes is relatively large, to ensure safe operation of the blockchain system, the authentication system may be deployed at some blockchain link points, for example, the authentication system is deployed at all the blockchain nodes, and the authentication system is deployed at some blockchain light nodes; alternatively, the authentication system is deployed on a small number of blockchain full nodes, and the authentication system is deployed on all blockchain light nodes. For this reason, the solution of this embodiment is only for the blockchain node where the authentication system is deployed.
Optionally, in an implementation manner of this embodiment, the internet system is a blockchain system, the first internet node is a first blockchain node, and the second internet node is a second blockchain node.

analyzing a second part of trust certification on the link point of the second block to obtain a second neighbor trust certification;
and mutually authenticating the first internet node and the second internet node according to the first neighbor credibility certificate in the first internet node and the second neighbor credibility certificate of the second internet node.
In this embodiment, the execution subject of the above steps may be an authentication kernel in an authentication system.

Specifically, in this embodiment, the first partial trust certificate may be recorded in the first authentication entry, and the first partial trust certificate may be recorded in the second authentication entry.
Optionally, in an implementation manner of this embodiment, the first block link node and the second block link node are directly adjacent or indirectly adjacent; if the first block chain node and the second block chain link point are indirectly adjacent, the first part of trust certificate of the first block chain node is obtained by aggregating the trust certificates of the block chain link points directly adjacent to the first block chain node, and the second part of trust certificate of the second block chain node is obtained by aggregating the trust certificates of the block chain link points directly adjacent to the second block chain node.
In this embodiment, in order to comprehensively evaluate trust of a certain block chain node in a block chain system, it is considered that, for a block chain link point adjacent to a certain block chain link point, not only directly adjacent but also indirectly adjacent, for this reason, when aggregation is performed, a part of trust certificates of the block chain link point indirectly adjacent to the certain block chain link point are aggregated to the block chain node directly adjacent to the certain block chain link point on the basis of the directly adjacent block chain link point, so that trust transfer is realized, and when the trust transfer idea is applied to a first block chain node and a second block chain node which are in communication, trust evaluation is performed between the two block chain nodes.
