摘要
工业互联网的发展极大地提升了工业企业的数字化和智能化水平,工业数据资产已经成为一种越来越重要的战略资源和新型生产要素,如何保证工业数据从创建、授权、共享到收益分配的全生命周期安全可信是当前需要解决的首要问题。为此,基于工业数据资产价值流转系统的设计目标,提出基于区块链的工业数据资产可信确权和价值流转框架,构建适用性和可扩展性较强的一般性框架和具体方案,给出了在数据多方参与、多次共享的工业场景下具体保障工业数据资产在确权、访问、收益全流程可信可控的解决方案和流程。为解决安全和效率的矛盾问题,提出了一种轻量级可信区块链模型。基于节点的行为和状态度量节点的可信度,给出节点的动态初始值计算式和整体信任值度量模型信任管理,并基于节点的可信度优化区块链系统共识协议算法,在降低节点恶意攻击概率的同时提高了系统交易共识效率,实现整体系统的安全和轻量级并行。最后通过仿真实验验证了新方案的优越性。
The development of industrial Internet has greatly improved the digital and intelligent level of industrial enterprises.Industrial data assets have become an increasingly important strategic resource and new production factor.How to ensure the security and credibility of industrial data in the whole life cycle from creation,authorization,sharing and income distribution is the primary problem to be solved at present.To this end,based on the design goal of the industrial data asset value transfer system,a blockchain-based framework for trusted ownership confirmation and value transfer of data assets was proposed,a general framework and specific solution with strong applicability and scalability were constructed,and specific solutions and processes were provided to ensure the trustworthiness and controllability of industrial data assets throughout the entire process of ownership confirmation,access,and revenue sharing in an industrial scenario where data was involved from multiple parties and shared multiple times.To solve the contradiction between security and efficiency,a lightweight trusted blockchain model was proposed,which measured the trustworthiness of nodes based on their behavior and status,and provided a dynamic initial value calculation method for nodes and an overall trust value measurement model for trust management.The consensus protocol algorithm of the blockchain system was optimized based on the trustworthiness of nodes,reducing the probability of malicious attacks on nodes while improving the efficiency of system transaction consensus,achieving security and lightweight parallelism of the entire system.Finally,the superiority of this scheme was verified through simulation experiments.
