基于图像信息隐藏的能源区块链私钥存储算法
|
摘要
可靠的私钥存储是能源区块链业务安全性的必要保障,为了提高区块链私钥存储技术在新型能源交易模式的安全性,本文提出了基于图像信息隐藏的能源区块链私钥存储算法。首先在原始私钥的基础上增加随机数以及纠错码,生成水印信息,再通过离散小波变换将图像信息转化为系数矩阵,并引入量化索引调制的方法实现水印信息的嵌入。最后通过实例分析证明该算法能有效地提高能源区块链私钥存储的安全性,能够准确地提取出私钥,同时针对嵌有私钥的水印图像可能遭受的攻击,有良好的透明性和鲁棒性。
Reliable private key storage is a necessary guarantee for the security of energy blockchain business. To improve the security of the blockchain private key storage technology in a novel energy trading mode,an energy block-chain private key storage algorithm based on image information hiding is proposed. First,a random number and an error correction code are added to the original private key to generate watermark information. Then,the image information is transformed into a coefficient matrix by discrete wavelet transform,and the quantization index modulation method is introduced to embed the watermark information. Finally,the analysis of an example proves that this algorithm can effectively improve the security of energy blockchain private key storage and accurately extract the private key;meanwhile,it has satisfying transparency and robustness against the attacks that the watermark image embedded with the private key may suffer.
