Description
Technical Field
The invention belongs to the technical field of network security, and particularly relates to an industrial internet data security management system and method based on a block chain.
Background
In the conventional internet, common data security mechanisms include a method of encrypting data using various encryption algorithms and then transmitting the encrypted data, a method of limiting a visible range of the data by access right hierarchy, and the like. For a data encryption transmission mechanism, data is encrypted mainly through common data encryption algorithms such as an MD5 algorithm, an SHA1 algorithm and the like, and is decrypted after transmission is completed, so that safe transmission is realized; for an access authority grading mechanism, user authority is mainly distributed and judged through a grouping management-control process, and grading safe access of data is achieved.
The industrial internet is an industry and application ecology formed by the omnibearing deep integration of the internet, a new generation information technology and an industrial system, and is a key comprehensive information infrastructure for industrial intelligent development. The industrial internet is used as a key comprehensive information infrastructure for industrial intelligent development, is an important carrier for digitalization, networking and intellectualization of the manufacturing industry, is oriented to the digitalization, networking and intellectualization requirements of the manufacturing industry, constructs a service system based on mass data acquisition, aggregation and analysis, and is an important foundation for the construction of the strong country of China and the strong network country. The industrial internet relates to various support technologies, including industrial PON, industrial sensing and control, big data, cloud computing, and the like. These technologies cover different aspects of industrial processes, such as analysis, storage, sensing, connectivity, automation, Human Machine Interaction (HMI) and manufacturing. Although the industrial internet has achieved certain development results in theory and practice, many challenges still exist, and the most urgent one is to solve the security problem in the industrial data circulation process. Since most of the devices in the factory network only have simple data interaction capability and are difficult to implement data encryption transmission function required by a common data security mechanism, the security problem in the industrial data circulation process is difficult to solve by using a traditional method, and the block chain technology is widely used as an emerging data security technology to solve the problem.
A blockchain is in fact a distributed computing and storage system that is stored between multiple participants in a peer-to-peer network, and the participants can add new transactions to an existing transaction chain using encrypted signatures, forming a secure, continuous, invariant chained data structure. The block chain has the characteristics of tamper resistance, decentralization, multi-party participation and the like, and can effectively reduce trust cost generated by a centralization structure.
Currently, a common block chain data circulation security mechanism in the industrial field includes a dynamic data tracing method, a data sharing method, an access control method and the like based on a alliance chain. The principle of the dynamic data tracing method based on the alliance chain is that a multi-dimensional DAG graph is constructed and a dynamic data security model is established, wherein the multi-dimensional DAG graph determines the multi-dimensional authorization condition of a parent node and a child node according to the node in-degree and out-degree, a directed edge represents an evolution track under the dynamic data execution operation, an entity authorization relation is generated according to the dynamic data, the entity authorization relation and a key pair used for the entity to authorize and verify the dynamic data, the entity authorization relation is generated according to the boundary condition that each node achieves consensus, the multi-dimensional authorization chain between the entities is established and issued as a transaction to an authorization relation alliance chain network to be stored in a block chain form, and therefore trace and source tracing of the dynamic data operation of the Internet of things are achieved. It should be noted that, at present, a data security management mechanism completely adapted to an industrial internet scenario is not available, and a similar data tracing mechanism based on a DAG graph is mainly applied to the field of internet of things and cannot completely adapt to the requirements of the field of industrial internet.
The block chain technology is introduced in the field of industrial internet, so that the problems of data security and data concentration in the data circulation process of the industrial internet are solved, and the problems of data security circulation in new scenes and new applications emerging in the development process of the industrial internet such as commodity tracing, intelligent logistics and the like are realized through an intelligent contract, but under the background of the industrial internet, the block chain technology still has the following defects:
1. the existing data security scheme is multi-sided to the security protection of the data on the chain, and the security protection of the data off the chain is not enough. For a general data security management mechanism, the key point of management is to manage and control data on a chain, for example, a data management traceability technology implemented based on a DAG graph, the key point of the management is to create a multidimensional authorization chain between entities in a network and issue the multidimensional authorization chain as a transaction to an authorization relationship network, so as to implement operation trace and traceability of data on a link of an internet of things, and to prevent an attacker from performing operations such as tampering and illegal access on dynamic data of the internet of things, and not to relate to management and security protection of data under the chain.
2. The existing data security protection scheme is based on a static execution strategy and cannot cope with the situation of dynamic change. For a mainstream data security management mechanism, a static data access and modification policy is mostly based, that is, a user defines each authority of the user when joining a system, determines the authority previously entered by the user when the user performs each operation, and opens a corresponding authority to the user. However, for the field of industrial internet, there are behaviors such as information interaction, sharing, transaction and the like often among organizations and users, the authority of a user on certain data needs to be changed in real time, and a static execution strategy cannot meet the requirement.
3. The safety and the operation performance of the existing data safety protection scheme are difficult to meet the use requirement of an industrial internet system. For a data security mechanism adopting a DAG graph, the operation performance is high, and the concurrency is good, but the security and the consistency have some problems in terms of data structures; the trusted distributed data security method adopting the P2P technology has some problems in operation performance, and cannot simultaneously meet the use requirements of industrial internet security and operation performance.
In view of the above, there is a need to develop an industrial data security management mechanism that can meet the security, management and performance requirements of the industrial internet system.

Detailed Description
1. Block chain-based industrial internet data security management system functional module design
As shown in fig. 1, the industrial data security management system designed by the present invention includes five functional modules, which are used to ensure the secure circulation and operation tracing of data in the industrial internet, implement the functions of authorization management, trust endorsement, accounting storage, etc. of users through a permission chain, and implement the storage, verification and analysis of data on the off-chain and on-chain through each functional module.

The data management and control module is responsible for storing various data, including a hash corresponding to the off-link data storage address, a hash corresponding to the off-link data abstract, operation permissions corresponding to the data and the like. The control module is responsible for analyzing and verifying the requests sent by the data management and control module, the data verification module and the data management module, and forwarding the requests to the corresponding modules. The data management module is responsible for performing operations such as registration, updating, deletion, query and the like on the data on the chain, and the data verification subsystem is responsible for verifying the data on the chain and the off-chain and confirming whether the data is tampered and when the data is tampered.
Specifically, a User Join Module (User Join Module, UJM) sends User feature information and an initial Data operation authority of a User to a Data Management Module (DMM), and the Data Management Module is responsible for receiving the User feature information and the initial Data operation authority and recording the User feature information and the initial Data operation authority into a block chain. The data management and Control Module stores all on-chain data, including user information, corresponding authority, off-chain data storage address and corresponding hash, hash value corresponding to off-chain data abstract, and on-chain data, interacts with a Control Module (CM), and returns various query requests of the Control Module. The control module is responsible for interfacing with other modules, such as receiving a query request of the data verification module and returning a corresponding result. And the Data Verification Module (DVM) is responsible for verifying Data on an off-link or on-link, sending the hash of the current Data storage address and the hash of the product information, comparing and verifying the hash value stored on the link by the control Module, and returning the Verification result of the Data Verification subsystem. The Data Control Module (DCM) is responsible for performing operations such as registration, modification, deletion and the like on the linked Data, and interacts with the Control subsystem to obtain confirmation information of successful operation.
The original blockchain system has certain limits in performance and the amount of data that can be stored is limited. For example, the Bitstone network, with a block size of only 1MB and only up to 2000 transactions, can greatly limit the industrial data chaining. The system divides data into two parts, off-chain data only stores corresponding hash values on a chain, and data bodies are not stored on a block chain. When the data is verified, whether the data is falsified can be verified only by verifying whether the corresponding hash values are consistent.
