With the rise of edge computing, applications have entered the age of end-edge cloud collaboration. In the data transmission and processing process under the cooperation of the end-edge cloud, the edge is responsible for bearing a part of cloud tasks, and after the end-edge cloud finishes calculation, the result is uploaded to the cloud so that the cloud can perceive the state of the terminal and generate an optimal control strategy. For example, in a security monitoring scene, terminal devices such as an intelligent camera and an intelligent sensor collect environmental data, the data are uploaded to edge nodes such as an edge gateway and an edge base station to process and perceive environmental states and abnormal early warning, cloud based on analysis and reporting results of edges realize global perception of the environment of the whole application system, and timely perceive the occurrence of security events and arrange other resource disposal early warning events. The authenticity of the edge forwarding or processing results is therefore very important for both the terminal and the cloud.

Detailed Description
The following describes the embodiments of the present invention further with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present invention, and are not intended to limit the scope of the present invention.
Fig. 1 is a schematic diagram of a system for transmitting data and processing trusted authentication according to an embodiment of the present invention, where the system includes: terminal 100, edge node 200, cloud server 300.
The terminal 100 is configured to add a feature element to the first data according to the first feature element adding mechanism, so as to obtain second data;
the cloud server 300 is configured to send the first feature element adding mechanism to the 2 nd edge node 200;
the 2 nd edge node 200 is configured to determine whether the second data processed by the 1 st edge node conforms to the first characteristic element adding mechanism; if yes, the 1 st edge node trusted authentication passes;
the (N-1) th edge node 200 is configured to add a feature element to the data processed by the (N-1) th edge node according to the (N) th feature element adding mechanism; performing trusted authentication on the Nth edge node; if the trusted authentication is passed, continuing to perform the trusted authentication on the (n+1) th edge node, otherwise, ending the trusted authentication.
It should be noted that fig. 1 is only an example of a system architecture according to an embodiment of the present invention, and the present invention is not limited thereto in particular.
Further, as shown in fig. 2, a schematic diagram of a system for transmitting data and processing trusted authentication is provided in an embodiment of the present invention.
As can be seen from the figure, when the terminal uploads data to the cloud server through the edge node, firstly, feature elements negotiated with the cloud server are added into the original data according to a feature element adding mechanism to form brand new original data. The modified data is uploaded to an edge node for forwarding or model processing, and the edge node uploads the output data to a cloud server. And the cloud server judges whether the output data of the edge node accords with the negotiated characteristic element and characteristic element adding mechanism. If so, the data transmission or processing procedure from the terminal to the edge node to the cloud server is indicated to be safe and reliable, otherwise, the data is indicated to exist on the communication link with an untrusted edge node and the data has been modified.
Based on the above system for data transmission and trusted authentication processing, fig. 3 illustrates a flow of a method for data transmission and trusted authentication processing provided in an embodiment of the present invention. The process may be performed by the system for data transmission and trusted authentication described above.
As shown in fig. 3, the process specifically includes:
In the embodiment of the invention, before the Nth characteristic element adding mechanism is obtained, a first characteristic element adding mechanism is obtained;
it should be noted that, the first feature element adding mechanism is determined by the terminal and the cloud server.
Adding characteristic elements into the original data acquired by the terminal according to a first characteristic element adding mechanism;
transmitting a first characteristic element adding mechanism to a 2 nd edge node through a cloud server;
judging whether the data processed by the 1 st edge node accords with a first characteristic element adding mechanism or not through the 2 nd edge node;
if yes, the 1 st edge node passes the trusted authentication, otherwise the trusted authentication is ended.
In the embodiment of the invention, if the data transmission processing from the terminal to the 1 st edge node to the 2 nd edge node is accordant, the data transmission processing is safe and reliable; otherwise, it indicates that there is an untrusted node on the communication link, i.e., the 1 st edge node is not trusted, and that the data has been modified by the 1 st edge node.
And step 302, adding characteristic elements to the data processed by the N-1 th edge node according to the N characteristic element adding mechanism to obtain characteristic element data.
It should be noted that, the nth characteristic element adding mechanism is determined by the nth-1 edge node and the cloud server. Wherein N is an integer not less than 2.
In the embodiment of the invention, when the terminal is registered in the edge computing system, a group of characteristic elements and a characteristic element adding mechanism are determined with the cloud server.
Specifically, the terminal and the cloud server select data consistent with the scene according to the application scene, so that the influence of the characteristic elements on the original data is reduced, and the influence on the normal service of the edge computing system based on the data is avoided.
For example, the data transmitted to the cloud server by the terminal is a picture, the content of the picture is that different kinds of fruits are placed on the dining table, and the fruits are apples, bananas and grapes respectively. At this time, the terminal and the cloud server agree that the characteristic elements are apples, bananas and grapes.
Further, the feature element adding mechanism means that the position of adding the feature element meets a certain constraint condition.
For example, the position where 3 feature elements are added satisfies a specific shape such as a triangle, or the position is selected at a preset position, or the like.
For example, after the terminal and the cloud server agree that the characteristic elements are apples, bananas and grapes, the terminal adds the characteristic elements including apples, bananas and grapes on the original picture, and enables the three characteristic elements of the apples, the bananas and the grapes to meet the positional relationship of three vertexes of the equilateral triangle.
According to the scheme, the trusted authentication efficiency and the trusted authentication convenience are improved through the characteristic element adding mechanism.
And 303, transmitting the characteristic element data to the nth edge node so that the (n+1) th edge node can judge whether the data processed by the nth edge node accords with an nth characteristic element adding mechanism.
For example, the 2 nd edge node obtains data from the 1 st edge node to see if the first feature element addition mechanism is met.
In the embodiment of the invention, the trusted authentication of the Nth edge node is completed through the (N+1) th edge node on the communication link. And a newly-built communication channel is not formed between the terminal and the cloud server, and continuous connection is not required to be maintained.
It should be noted that, the embodiment of the invention is not only suitable for the trusted authentication of data transmission from the terminal to the edge node and then to the cloud server, but also suitable for the collaborative authentication of correctness of the collaborative data processing result among the terminal, the edge node and the cloud server.
In the embodiment of the invention, the terminal negotiates a group of characteristic elements and a characteristic element adding mechanism with a cloud server when the terminal is added to an edge computing system for the first time. When the terminal uploads data to the cloud server through the edge node, firstly, adding feature elements negotiated with the cloud server into the original data according to a feature element adding mechanism to form brand new original data.
Further, the modified data is uploaded to an edge node for forwarding or model processing, and the edge node uploads the output data to a cloud server. And the cloud server judges whether the output data of the edge node accords with the negotiated characteristic element and characteristic element adding mechanism. If so, the data transmission or processing procedure from the terminal to the edge node to the cloud server is indicated to be safe and reliable, otherwise, the data is indicated to exist on the communication link with an untrusted edge node and the data has been modified.
In the embodiment of the invention, when the edge computing system only has 1 edge node, the cloud server judges whether the second data processed by the 1 st edge node accords with the first characteristic element adding mechanism. When only one edge node exists, the terminal and the cloud server finish the trusted authentication, and the edge does not need to be modified.
Further, when the edge computing system has a plurality of edge nodes, the trusted authentication task is downloaded to the plurality of edge nodes through the cloud server.
In the embodiment of the invention, the crosstalk between different edge nodes leaks the related parameters of the trusted authentication, which leads to the failure of the trusted authentication result, so the embodiment of the invention prevents the crosstalk between different edge nodes based on the game theory.
Specifically, before step 301, the embodiment of the present invention obtains an edge node newly added to a data transmission link;
sending an intelligent contract to an edge node newly added into a data transmission link through a cloud server;
and allowing the edge node newly added into the data transmission link to be added after the edge node newly added into the data transmission link signs an intelligent contract.
In the embodiment of the invention, the cloud server requires the edge nodes participating in the edge computing system to make an intelligent contract with the cloud server when joining the edge nodes to the system.
The smart contracts aim to penalize an edge node when that node is found to have dishonest behavior.
For example, the edge node pays a portion of the deposit as a deposit for trusted data transmission or processing by contracting with the cloud server for an intelligent contract. When dishonest behavior is found, the deposit will be withheld.
Note that dishonest behavior includes collusion between edge nodes and trusted authentication of edge nodes not passing.
Further, after the first feature element adding mechanism is sent to the 2 nd edge node through the cloud server, the embodiment of the invention further includes:
judging whether report information from the 1 st edge node is received or not through a cloud server;
in one possible implementation, the reporting information includes signature information of the 2 nd edge node.
Specifically, the 1 st edge node signs contracts with the 2 nd edge node through intelligent contracts of the blockchain, so that the aim of collusion with the 2 nd edge node is fulfilled.
And if the intelligent contract is received, modifying the parameters of the intelligent contract corresponding to the 1 st edge node according to the parameters of the intelligent contract corresponding to the 2 nd edge node.
Specifically, if the 2 nd edge node agrees to sign a contract with the 1 st edge node, the 1 st edge node reports dishonest behavior of the 2 nd edge node to the cloud server.
Further, before the (n+1) th edge node judges whether the data processed by the (N) th edge node accords with the (N) th characteristic element adding mechanism, the (N) th characteristic element adding mechanism is sent to the (n+1) th edge node through the cloud server;
judging whether report information from an Nth edge node is received or not through a cloud server;
and if so, modifying the parameters of the intelligent contract corresponding to the N edge node according to the parameters of the intelligent contract corresponding to the N+1th edge node.
For example, to prevent collusion between edge nodes, cloud servers destroy the reliability of trusted authentication. After the cloud server reports dishonest behavior of the (n+1) th edge node, the cloud server will not punish the (n+1) th edge node and rewards the (n+1) th edge node with deposit as long as other unreliable edge nodes in the edge computing system are grasped before the (N) th edge node.
In the embodiment of the invention, the cloud server causes the situation of mutual distrusting among different edge nodes, so that each reasonable edge node finds that the gain of collusion is less than the gain of honest in games, and therefore, collusion is not selected to destroy the trusted authentication.
Further, after the trusted authentication is finished, the embodiment of the invention further comprises:
and modifying the parameters of the intelligent contracts corresponding to the (n+1) th edge node by the cloud server according to the parameters of the intelligent contracts corresponding to the (N) th edge node.
For example, the cloud server rewards the n+1th edge node with the deposit of the N edge node after the n+1th edge node authenticates that the N edge node is not trusted.
The embodiment of the invention is suitable for the data uploading stage from the terminal to the cloud server and also suitable for the data downloading stage from the cloud server to the terminal. Meanwhile, the embodiment of the invention can be applied to any trusted authentication task of the communication link with the intermediate node.
According to the scheme, the trusted authentication task is lowered to each edge node and mutual distrustion among different edge nodes is manufactured, so that the trusted authentication task is prevented from being destroyed by the edge nodes through collusion, the trusted authentication from the terminal to the edge nodes to the cloud server is guaranteed, and the trusted authentication in data processing and data transmission can be supported.
