Research on Security Access Control Method of Energy Data Based on Perceptual Hash
As an important step to ensure the security of energy data,the access control process is susceptible to the interference of data variability,imbalance,redundancy,and other problems,which leads to an increase in the security access control time,a decrease in the success rate of the interaction and an increase in the computational overhead.To effectively solve this problem,the secerity access control method of energy data based on perceptual Hash is proposed.Supervised discriminative projection algorithm is used to do dimensionality reduction on energy data to reduce the redundancy between information.Distributed storage data is obtained by using the perceptual Hash algorithm.By combining the binary primary function induction algorithm,the secret key is generated in the distributed storage data.The dynamic change of data authorization access is achieved,through the control strategy combining inner layer encryption and outer layer encryption,so that the security access control of energy data is completed.The experimental results show that the method has a short energy data security access control time,a high interaction success rate,and a small computational overhead.This method can provide important reference for further development in the field of energy data security.
