Problems solved by technology

In addition to increasing the computing and storage pressure of fog nodes, this combination of conventional methods has a limited degree of security improvement and does not reduce the cost of computing and storage capabilities. In particular, these conventional methods cannot effectively prevent attacks on fog environments. new security attack
Patent document CN111372243A faces the same problem. It adopts a Byzantine fault-tolerant formula mechanism suitable for alliance chains to realize mutual supervision and fast verification of blocks, but it still cannot filter out malicious nodes or dishonest nodes. Therefore, it adopts access based on a security threshold multi-party protocol Control mechanism, when there are few malicious nodes or dishonest nodes, the system can run normally, but there are still security risks, although it also proposes that a lightweight encryption algorithm can be used to achieve identity verification, which can ensure data privacy. However, the improvement of the same security level is limited, it cannot solve new security attacks, and more importantly, its data cannot guarantee the authenticity
Therefore, this patent proposes a combination of bilinear pairing and batch verification technology. Compared with the privacy protection scheme of Efficient Privacy-Preserving Demand Response (EPPDR) dynamic encryption, by incorporating batch verification technology into the verification mechanism, it reduces The number of time-consuming bilinear pairing operations effectively reduces the computational overhead. Compared with the block confirmation speed of the traditional blockchain, it is nearly 6 times faster, although the technical solution of this patent document reduces the number of matching operations. Reduce computing overhead, but the degree of reduction in computing overhead still cannot meet the requirements of the Internet of Things for lightweight performance

Embodiment 1

[0100] Such as figure 1 As shown, the IoT fog environment management architecture based on blockchain technology provided by this embodiment includes at least fog nodes 100 . A plurality of fog nodes 100 constitute a fog environment 400 . Preferably, as figure 1 As shown, many sensing devices under the local Internet of Things collect the source data of the physical world, and aggregate it to the key nodes of the local Internet of Things (such as gateways and other devices), and temporarily store and preprocess it for subsequent use. Several local area networks establish a fog environment 400 capable of communicating with each other through wired or wireless transmission. On the one hand, the fog environment 400 can be connected to the cloud 200, such as a remote cloud server. At the same time, the fog environment 400 is relatively close to the terminal node 300 device of the user 20 . Therefore, it can be said that the fog environment 400 is a bridge for establishing a tr...

Embodiment 2

[0141] This embodiment is a further improvement / supplement to Embodiment 1, and repeated content will not be repeated.

[0142] This embodiment provides a method for managing the fog environment of the Internet of Things based on blockchain technology. The method includes:

[0143] S100: Divide multiple fog nodes 100 in the IoT fog environment into a first type of blockchain 600 and a second type of blockchain 700; preferably, the IoT environment management method based on blockchain technology in this embodiment A management framework is deployed between the fog nodes 100 or between the fog nodes 100 and the cloud 200 . Such as figure 2 As shown, the management architecture includes at least two types of blockchains constructed by multiple fog nodes 100 . The two types of blockchains are respectively the first type of blockchain 600 and the second type of blockchain 700 . Preferably, the fog nodes 100 in the first type of blockchain 600 perform identity verification befor...

Embodiment 3

[0178] This embodiment is a performance test of the IoT fog environment management framework and method provided in Embodiment 1 and Embodiment 2, in order to illustrate the technical effect of the present invention.

[0179] Preferably, the performance test includes two parts: functional experiment and performance experiment. The function experiment is used to verify whether the scheme can meet the identity detection requirements of the fog node 100 device in the fog environment 400. That is, before the data transmission process starts, it is confirmed that the identity of the node is legal, and the original data stored in it is credible and available. In addition, it is verified whether the scheme can meet the needs of data management between devices in the fog environment 400, that is, to realize functions such as data addition and sharing under the premise of ensuring the security of data transmission, and to perform search and modification synchronously between different n...

Abstract

The invention relates to an Internet of Things fog environment management architecture and method based on a blockchain technology, and the architecture at least comprises at least one first type of blockchain which is constructed by a plurality of fog nodes in an Internet of Things fog environment, and constructs a second type of blockchain based on at least one fog node on the first type of blockchain. The first type of blockchain is configured to perform identity verification on the fog node before the fog node sends data, and share private first data in a non-public mode based on an identity verification result; and the second type of blockchain is configured to monitor an identity verification result published by a fog node shared by the second type of blockchain and the first type ofblockchain and second data publicizable about the first data in a public chain manner. By means of the setting mode, decentration can be achieved, meanwhile, the performance requirement is lowered, and the identity verification accuracy is improved in the mode that the number of fog nodes is not related to the identity.
