基于区块链高效安全的多部门铁路工程数据访问控制策略
Efficient and secure blockchain-based multi-sector railway engineering data access control strategy
摘要
Abstract
The data resources among various participating departments in railroad engineering construction have the problems of poor sharing efficiency,low utilization rate,and inadequate security.To overcome the deficiencies of the existing railroad engineering data platform,this paper proposed a blockchain-based(Blockchain)railroad engineering data sharing and security storage scheme.Within the engineering construction platform,Outsourcing-Attribute Based Encryption technology(OABE),Blockchain technology Interplanetary File System(IPFS),and Edge Nodes(EN)were introduced.Edge Nodes(EN)proposed a collaborative network of multi-departmental blockchains and IPFS for railroad engineering construction.The research results show that when the construction site resources and equipment are limited,as compared to the more traditional cloud-assisted Ciphertext Policy Attribute Based Encryption(CP-ABE).Through outsourcing the railroad engineering data to the Edge Nodes,it can better provide a large number of computations for the resource-constrained equipment,reduce the computational burden of the equipment,and ensure that the equipment can be used for the construction of the railroad engineering.Outsourcing the railway engineering data to the edge nodes can better provide a large amount of computation for the resource-limited equipment,reduce the computation burden of the equipment,ensure data security,and improve the computation efficiency of the equipment.Moreover,storing railroad engineering data on the interstellar file system avoids data loss and leakage caused by centralized server mechanisms in case of failure.In addition,blockchain networks can improve the efficiency of data resource sharing between the participating units,enhance the data utilization rate,and utilize the blockchain's consensus to realize data consistency between each participating unit.This ensures trust between different participating units.After security proof,it is safe to adopt the Decision q-Bilinear Diffie Hellman Exponent Assumption(q-BDHE)with indistinguishability under the Bilinear Diffie Hellman Exponent Assumption(q-BDHE).Experimental results show that this strategy is optimal in terms of local user computation time efficiency compared to existing outsourced attribute-based encryption schemes with keyword search and attribute-based encryption,which effectively reduces the computational burden of field devices.关键词
