基于联盟区块链的放射源溯源数据存储优化

放射源监管部门为实现放射源可靠、安全、高效地流转,需要一套完善的放射源监管机制,及时对放射源的状况进行实时报备。在现有的放射源溯源体系中,放射源企业间的流转信息需要上传到本地监管部门进行实时存储,但是这种中心化的存储方式容易引起中心节点遭受恶意攻击而发生单点失效、数据被故意篡改等信息安全问题。针对放射源溯源信息安全问题,利用联盟区块链技术与监管部门构造联盟区块链溯源存储模型。由于记录放射源溯源信息是海量数据,在现有区块链技术下,网络中单节点的性能较低、同时数据存储采用链式本地存储导致无法平行扩展。因此结合放射源溯源数据的特点,提出一种分片存储方式以及区块节点的分组方式,提高节点处理放射源溯源数据的性能。

Secure Storage and Storage Optimization of Radioactive Source Traceability Data Based on Alliance Block

In order to achieve reliable,safe and efficient circulation of radioactive sources,the regulatory authorities of radioactive sources need a set of perfect regulatory mechanism for radioactive sources,and timely real-time preparation of the status of radioactive sources.In the existing traceability system of radioactive sources,the transfer information between radioactive sources enterprises needs to be uploaded to local regulatory authorities for real-time storage,but this centralized storage method can easily lead to malicious attacks on central nodes and single point failure,deliberate tampering of data and other information security problems.Aiming at the information security problem of radioactive source traceability,the block chain technology and supervision department are used to construct the alliance block chain.Because the traceability information of radioactive sources is massive data,under the existing block chain technology,the performance of single node in the network is low,and the data storage can not be expanded parallel because of the chain local storage.Therefore,in this paper,we propose a method of segmenting and storing radioactive source traceable data to improve the performance of node processing radioactive source traceable data.
