基于区块链技术的建筑材料供应链质量数据安全共享方法

传统方法在建筑材料供应链质量数据安全共享中应用效果不佳，不仅数据误码率比较高，而且数据共享时延比较长，无法达到预期的数据安全共享效果。为此提出基于区块链技术的建筑材料供应链质量数据安全共享方法。利用区块链技术对建筑材料供应链质量数据属性加密，建立建筑材料供应链质量数据安全共享链，整合建筑材料供应链质量数据加密、解密程序，通过对用户身份验证实现对质量数据安全共享，以此完成基于区块链技术的建筑材料供应链质量数据安全共享。实验证明，设计方法的数据误码率在1%以内，数据共享时延在1s以内，具有良好的数据安全共享效果。

Safety Sharing Method of Quality Data in Building Materials Supply Chain Based on Blockchain Technology

The application effect of traditional methods in the quality data security sharing of construction materials supply chain is poor, not only the data error rate is relatively high, but also the data sharing delay is relatively long, which can not achieve the expected data security sharing effect. Therefore, a quality data security sharing method of construction materials supply chain based on blockchain technology is proposed. The blockchain technology is used to encrypt the quality data attributes of the building materials supply chain, establish the quality data security sharing chain of the building materials supply chain, integrate the encryption and decryption procedures of the quality data of the building materials supply chain, and realize the quality data security sharing through user identity verification, so as to complete the quality data security sharing of the building materials supply chain based on the blockchain technology. Experiments show that the design method has good data security sharing effect when the bit error rate of low quality data is less than 1% and the data sharing delay is less than 1 second.
