Problems solved by technology

These data need to be transmitted to the cloud server center for computing and storage services, which poses a big challenge to the performance and network bandwidth of the cloud platform, and the centralized processing of data on the cloud platform also brings many risks, which need to be transmitted to the cloud platform. Massive data flow puts enormous pressure on the entire network
At the same time, since a single point of failure is an inevitable hidden danger, it is difficult for the central server to guarantee network security; in order to solve the above problems, people have introduced edge computing
[0003] Edge computing is a new computing paradigm that can transfer the pre-processing of applications, private data storage, and real-time data processing and analysis from the cloud server center to the edge server of the network, thereby retaining the core advantages of cloud computing and integrating real-time Control and sensitive data are stored on the edge server, but edge computing also has security and privacy issues, such as authentication, intrusion detection, access control, etc. in the edge computing architecture are easily cracked and cannot guarantee security, thus affecting edge computing usage of
[0004] Therefore, there is currently a need for a method to address the security issues of edge computing

Embodiment 1

[0026] Embodiment 1 of the present invention discloses a blockchain-based edge computing network architecture, such as figure 1 As shown, it includes: a terminal, an edge proxy layer with a private blockchain, an edge service layer with a public blockchain, and a cloud computing center; wherein, the terminal is connected to the edge service layer through the edge proxy layer ; The edge service layer is connected to the cloud computing center;

[0027] The edge agent layer is used to judge whether the terminal accessed is an authenticated terminal through the identity information of the authenticated terminal in the private block chain; if the judgment result is yes, then execute the data transmission and reception of the terminal;

[0028] The edge service layer is used to authenticate the edge agent layer through the identity authentication function in the public blockchain, and execute the request of the terminal if the authentication is passed.

[0029] Specifically, the r...

Embodiment 2

[0040] Embodiment 2 of the present invention also proposes a blockchain-based edge computing network architecture. On the basis of Embodiment 1, as figure 2 As shown, the terminal includes sensors for sensing the external environment and / or actuators for converting commands into physical actions.

[0041] Terminals: Terminals are divided into two categories: sensors, which are responsible for sensing the external environment, and actuators, which translate commands into physical actions. Usually, IoT terminals are limited by various resources and only act as producers or consumers at both ends of the data chain. In some cases, IoT device terminals have limited computing power and cannot preprocess raw data. The architecture of this patent allows IoT terminals to connect with nearby edge agent nodes through wireless or wired communication protocols (such as Zigbee, Bluetooth and NFC). The frequency of IoT terminal sensing services can be adjusted according to the system cont...

Embodiment 3

[0052] Embodiment 3 of the present invention also proposes a blockchain-based edge computing network architecture. On the basis of Embodiment 1 and Embodiment 2, the proxy node is provided with a proxy component; the proxy component includes: function mapping module, a device registration module, a block chain authentication module, and a high-speed channel; wherein, the function mapping module is used to obtain the information and address of each application on the edge server, manage the mapping information of different applications on the edge server, and The application information and application data are transmitted to the task queue of the edge server; the device registration module is used to register the terminal; the block chain authentication module is used to realize the connection between the application on the edge server and the Two-way authentication between terminals; the express channel is used to connect the cloud computing center.

Abstract

The invention provides an edge computing network architecture based on blockchain. The edge computing network architecture comprises a terminal, an edge agent layer, an edge service layer and a cloud computing center; the edge agent layer is used for judging whether the accessed terminal is an authenticated terminal or not according to the identity information of the authenticated terminal in the private blockchain; if the judgment result is yes, data sending and receiving of the terminal is executed; and the edge service layer is used for authenticating the edge agent layer through an identity authentication function in the public block chain, and executing the request of the terminal if the authentication is passed. The invention provides an edge computing network architecture based on a double-layer blockchain. And the terminal executes the function of the terminal on the edge agent layer according to the management of the private block chain and cannot directly communicate with the cloud computing center on the network. And the terminal completes data transmission and receiving services through the edge agent layer. And the edge service layer verifies the edge agent layer based on the public block chain, and the edge server initiates and executes a request of the terminal equipment after the verification is passed.

Description

technical field [0001] The present invention relates to the technical fields of edge computing and block chain, in particular to an edge computing network architecture based on block chain. Background technique [0002] In recent years, the Internet of Things has played an important role in the real world due to its powerful interconnection and interoperability features, promoting and promoting the widespread use of many emerging businesses in daily life. However, as the number of connected devices in the Internet of Things increases, the amount of real-time data generated and processed simultaneously increases exponentially. These data need to be transmitted to the cloud server center for computing and storage services, which poses a big challenge to the performance and network bandwidth of the cloud platform, and the centralized processing of data on the cloud platform also brings many risks, which need to be transmitted to the cloud platform. Massive data flows put enorm...
