基于区块链预言机的安全高效电力数据共享平台构建方法
Secure and efficient power data sharing platform construction approach based on blockchain oracle
摘要
Abstract
When taking the diversity of power data sharing,the privacy of power data and the large scale of power data into consideration,the existing data sharing platforms would suffer the following disadvantages:the low scalability and the poor security.For this reason,a secure and efficient power data sharing platform construction approach termed Pow-sharing was proposed.Firstly,a data sharing model based on collaborative multi-blockchain oracles was designed.To support both functional and performance scalability,a vertical division-based distributed oracle architecture was adopted,which followed the principle of high cohesion and low coupling.Next,to mitigate potential security threats in Powshar-ing(e.g.,privacy leakage,degradation attack and spoofing attack),a secure data sharing protocol was developed,incor-porating CKKS homomorphic encryption,ECDSA,and trust evaluation mechanisms.The rigorous theoretical analysis and extensive experimental verifications demonstrate that Powsharing significantly outperforms the prior works in terms of the efficiency and security.Specifically,Powsharing can achieve increased sharing efficiency(by about 15%)in com-parison to prior work,without leaking the data privacy.关键词
