Blockchain Based Trusted Identity Authentication in Ubiquitous Power Internet of Things

To solve the problem of data loss and malicious tampering caused by IoT devices without security verification during the implementation of smart grid projects, this paper utilizes the distributed ledger and non-tampering characteristics of blockchain technology to ensure the security of the stored data and to solve the problem of data reliability before winding. We design a hardware module based on the Ed25519 signature protocol combined with identity authentication technology to provide the identity key for IoT devices. By combining the two solutions, we can effectively solve the data security problems in the implementation of smart grid projects.
