为了解决当前物联网数据安全访问过程中存在的执行时间长、控制精度不足的问题，设计一种泛在电力物联网数据隐私安全防护访问控制技术。以泛在电力物联网的组织架构为基石，通过构建双向性映射机制建立访问决策域，实现对访问行为的精准界定。在决策域内部，应用线性秘密共享方案为不同层级的数据设置差异化的安全防护访问密钥。利用边缘计算算法，实现密钥与边缘节点的同步处理。实验结果表明，应用所设计技术后，控制精度稳定保持在90%以上，控制执行时间缩短至20 s以内，实现了高精度、高效率的访问控制，为泛在电力物联网的数据隐私安全提供了强有力的保障，具有较高的应用价值。

To solve the problems of long execution time and insufficient control accuracy in the current process of data security access in the Internet of Things, a data privacy and security protection and access control technology in the ubiquitous electric Internet of Things is designed. Based on the organizational structure of the ubiquitous power Internet of Things, a bidirectional mapping mechanism is constructed to establish an access decision domain and achieve precise definition of access behavior. Within the decision-making domain, linear secret sharing schemes are applied to set differentiated security protection access keys for data at different levels. Edge computing algorithm is used to synchronize the key and edge nodes. The experimental results show that after applying the designed technology, the control accuracy remains stable at over 90%, the control execution time is shortened to within 20 s, and high-precision and high-efficiency access control is achieved. This provides strong protection for data privacy and security in the ubiquitous electric Internet of Things, and has high application value.
