摘　　要：作为保证能源数据安全的重要步骤,访问控制过程易受数据差异性、不均衡性、冗余性等问题的干扰,导致安全访问控制时间增加、交互成功率下降以及计算开销增加。为了有效解决这一问题,提出基于感知哈希的能源数据安全访问控制方法。采用监督判别投影算法对能源数据做降维处理,以降低信息之间的冗余性。利用感知哈希算法,得到分布式存储数据。结合二元一次函数诱导算法,在分布式存储数据中生成密钥。通过内层加密与外层加密相结合的控制策略,实现数据授权访问的动态变化,完成能源数据的安全访问控制。试验结果表明,该方法的能源数据安全访问控制时间短、交互成功率高、计算开销小。该方法可为能源数据安全领域的进一步发展提供重要参考。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.
