摘要
Abstract
Reliable private key storage is a necessary guarantee for the security of energy blockchain business. To im?prove 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 in?troduced to embed the watermark information. Finally,the analysis of an example proves that this algorithm can effec?tively 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.关键词
