Security sharing method of monitoring data of power grid equipment based on improved certificateless signature
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 certifi-cateless signature is proposed.The certificateless signature method is improved by hash function and timestamp algorithm.The securi-ty 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 en-sure the security of data sharing.
