摘　　要：电力供应链资源安全共享能够提高电力供应链的效率和可靠性,实现资源的共享和优化利用。由于电力供应链中包含大量的隐私数据,一旦遭到黑客的攻击,会导致用户隐私泄露,影响电力供应链信息资源的安全性。为了有效解决上述问题,提出一种基于区块链的电力供应链信息资源安全共享方法。方法采用两个一维混沌系统建立复合混沌密码系统,并通过选择相关系数和均匀度指标建立综合目标函数。根据自适应混沌免疫粒子群优化算法对系统内的控制参数协调优化整定,以实现小波变换空间对明文信息的小波系数展开复合混沌加密。结合区块链技术建立电力供应链信息资源安全共享模型,完成电力供应链信息资源安全共享。实验结果表明,所提方法在样本数量为600个时,其计算时间保持在200ms内,有效提升系统运行效率,且系统开销小、吞吐量大,表明所提方法可以确保信息资源的安全共享。At present,the safe sharing of resources can improve the efficiency and reliability of the power supply chain,thus achieving resource sharing and optimized utilization.If the large amount of private data contained in the power supply chain is attacked by hackers,user privacy will leak,which affects the security of information resources in the power supply chain.In order to effectively address this issue,this article proposed a method of secure sharing for information resource in the power supply chain based on blockchain.This method used two one-dimensional chaotic systems to construct a composite chaotic cryptosystem,and established a comprehensive objective function by selecting correlation coefficients and uniformity indicators.According to the adaptive chaos immune particle swarm optimization,the method coordinated and optimized the control parameters in the system,so as to realize the composite chaotic encryption for the wavelet coefficients of plaintext information based on the wavelet transform space.Finally,a security sharing model for power supply chain information resources was built by blockchain technology,and then the security sharing of information resources in the power supply chain was completed.Experimental results show that when the number of samples is 600,the calculation time is kept within 200ms,so the proposed method effectively improves the system operation efficiency,with low overhead and huge throughput,indicating the safe sharing ability of information resources.
