摘　　要：【目的】电力监控系统承载着大量敏感信息,包括电力设备的运行数据、电力负荷情况及用户用电信息等。这些数据对保障电力系统的安全和稳定至关重要,因此保证这些数据的安全性是电力监控系统的关键。分布式数据库作为电力监控系统的核心组成部分,具有处理速度快、数据存储量大等优势,但也面临着数据泄露、非法访问等安全隐患。【方法】为了增强电力监控系统的安全性,提出了一种基于二叉Trie树的电力监控分布式数据库安全访问混沌加密控制方法。采用SRP-6协议进行身份认证,确保只有经过授权的用户能够访问电力监控系统。SRP-6协议通过对身份信息的加密处理,有效防止了恶意攻击者伪造身份访问。在分布式数据库的环境中,密钥的管理是极具挑战性的任务。由于分布式系统涉及多个节点,且不同用户的权限和密钥各不相同,因此需要建立一个高效且安全的密钥管理机制。本文采用了二叉Trie树作为密钥管理结构,二叉Trie树是一种能够快速检索和存储密钥的高效数据结构,通过二叉Trie树的层次化结构,实现密钥的快速定位和分配。每个节点代表密钥管理中的一个步骤,叶节点则存储具体的加密密钥。通过这种树形结构,系统可以轻松管理大量的密钥,减少了密钥存储的冗余,同时提高了密钥分发的效率。二叉Trie树的使用也降低了密钥泄露的风险,增强了系统的整体安全性。在密钥管理的基础上,引入混沌加密技术,结合Tent映射和Logistic映射两种混沌模型,用于生成加密数据所需的随机数和轮密钥。Tent映射通过折叠和扩展操作将输入值映射到[0,1)区间,而Logistic映射则通过迭代生成伪随机序列,两者共同构成了混沌加密的基础。通过这种方式,电力监控分布式数据库中的数据被加密为不可预测的密文,极大程度上提高了攻击者通过分析密文推导�[Objective]The power monitoring system carries a large amount of sensitive information,including the operation data of power equipment,power load conditions,and user power consumption information.Since these data are crucial to ensuring the safety and stability of the power system,it is a key issue in the power monitoring system to protect the security of these data.As a core component of the power monitoring system,the distributed database has advantages such as fast processing speed and large data storage capacity,but it also faces security risks such as data leakage and illegal access.[Methods]To enhance the security of the power monitoring system,this paper proposed a chaotic encryption control method for secure access to distributed databases of power monitoring based on a binary Trie tree.The SRP-6 protocol was used for identity authentication to ensure that only authorized users could access the power monitoring system.The SRP-6 protocol effectively prevented access of malicious attackers through forging identity by encrypting identity information.In the environment of distributed databases,key management was a highly challenging task.Since a distributed system involves multiple nodes,and different users have different permissions and keys,an efficient and secure key management mechanism was required.This paper took a binary Trie tree as the key management structure.Binary Trie trees are a kind of efficient data structure that can quickly retrieve and store keys.Through the hierarchical structure of a binary Trie tree,keys can be quickly located and allocated.Each node represents a step in key management,and leaf nodes store the specific encryption keys.Based on this tree structure,the system can easily manage a large number of keys,reduce the redundancy of key storage,and improve the efficiency of key distribution.The use of the binary Trie tree can also reduce the risk of key leakage and enhance the overall security of the system.On the basis of key management,chaotic encryption technology was introduced
