摘　　要：针对电网设备监测数据共享时效性差,用户个人信息易被窃取问题,提出一种基于改进无证书签名的电网设备监测数据安全共享方法。通过哈希函数、时间戳算法改进无证书签名方法,结合概率多项式、自适应选择身份建立数据共享的安全模型,使用合约、联盟区块链获取电网设备监测数据并发送,用户利用处理节点公钥加密请求信息并打包,处理节点通过自己的私钥解密用户发出密文,得到明文,再使用用户公钥对其加密并发送,最终用户得到电网设备的监测数据,实现信息共享。实验结果表明,所提方法共享效率较高,并能够保证数据共享的安全。Aiming at the problems of poor timeliness of monitoring data sharing of power grid equipment and the vulnerability of user’s personal information to theft,a security sharing method of monitoring data of power grid equipment based on improved certificateless signature is proposed.The certificateless signature method is improved by hash function and timestamp algorithm.The security model of data sharing is established by combining probability polynomial and adaptive identity selection.The contract and alliance blockchain are used to obtain the monitoring data of power grid equipment and send it.The user uses the public key of the processing node to encrypt the request information and package it.The processing node decrypts the encrypted text sent by the user through its own private key to obtain the clear text,and then uses the user’s public key to encrypt and send it,End users get monitoring data of power grid equipment to realize information sharing.The experimental results show that the proposed method is efficient and can ensure the security of data sharing.
