Research on data sharing security for smart grid blockchain and edge cluster
At present,smart grid is still facing problems such as weak privacy protection,poor security sharing ability,and heavy load of cloud center.Based on blockchain and edge cluster technology,the paper adopts the combination of distributed file storage system and alliance chain to realize the effective storage of power data,and adopts multi-signature notary technology to realize the safe sharing of power data.The results show that the calculation cost of the scheme is less than 0.1 s,the total time of encryption and de-cryption is about twice of the total time of re-encryption and decryption,and the time is slightly more,but it has higher security per-formance.The scheme can carry out data hiding and data privacy protection,and can prevent malicious tampering and resist attacks.The synchronization time of each node is less than 10 ms,and the average synchronization time will increase with the increase of the stored power data,but the increase is not large,with outstanding advantages in terms of confidentiality and security.This research provides a guarantee for the application of blockchain and edge clusters in smart grids.
