摘要： 随着电力网络通信系统的快速发展,大量数字化信息能够更加快捷有效地通过电力网络进行传输,但其在提高通信效率的同时,由于受网络攻击的风险日益增加因而也带来了隐私泄露、信息篡改等一系列安全性问题。在此背景下,特别是在无人巡检和设备远程监测等场景中,针对电力系统中相关缺陷信息的安全传输尤为重要。为确保信息传输的安全性,信息隐藏技术得到了广泛的研究与关注。针对目前信息隐藏技术普遍存在的低嵌入载荷、低安全性等问题,在综合考虑隐藏容量、隐写质量和安全性等因素后,提出了一种基于二阶数独矩阵的高载荷信息隐藏算法。该算法通过对原始数独进行扩展编码,旨在重构出新的二阶矩阵,其可引导每两位九进制数据以最小化失真的方式嵌入到原始图像的像素对中,从而实现高载荷信息隐藏的技术目标。其中,原始数独的选取由通信双方事先共享的密钥所决定,该密钥可通过量子密钥分发技术实现可靠传输,从而进一步提高算法的安全性。

Abstract: With the rapid development of power network communication systems,a large amount of digital information can be transmitted more efficiently through the power network.However,while improving communication efficiency,the increasing risk of network attacks brings a series of security issues such as privacy leakage and information tampering.In this context,especially in scenarios such as unmanned inspection and remote monitoring of equipment,secure transmission of relevant defect information in the power system is particularly important.Therefore,to ensure the security of information transmission,data hiding technology has received widespread research and attention.In view of the commonly existing problems of low embedding payload and low security in current data hiding technology,this paper proposes a high payload data hiding algorithm based on second-order Sudoku matrix after comprehensive consideration of factors such as hiding capacity,steganographic quality,and security.This algorithm extends and encodes the original Sudoku to reconstruct a new second-order matrix.It aims to guide every two nine-bit data to be embedded into pairs of pixels of the original image in a way that minimizes distortion,thus achieving the technical goal of high payload data hiding.The selection of the original Sudoku is determined by a secret key shared in advance by the communication parties,which can be reliably transmitted through quantum key distribution technology,further enhancing the security of the proposed algorithm.

Key words: Data hiding, Embedding payload, Power system, Secure communication, Quantum key distribution
