摘要
针对现有二维码技术保密性较弱的问题,提出一种应用于军事物联网中的图像加密技术。采用视觉加密手段,将传统的QR码图像生成2幅像素随机分布的共享图像,通过2幅共享图像的矩阵值的或运算,利用图像像素矩阵中的汉明重量w判断QR码原始图形中的黑白值,生成原QR码图像,达到QR码在授权设备中被还原并读取的目的。分析结果证明:该方法能克服传统QR码扫描技术的安全漏洞,加密后的QR码图像恢复效果好,并且保密性较强,在军事物联网的应用中有着广阔的前景。
The 2 dimension code is hard to keep secret, introduced an image cryptography technology for military internet of things. Adopt visual cryptography method, and transmit traditional QR code image to create 2 pixels random distribution share images. Through exclusive disjunction of 2 share image matrix value, use Hamming weight w of image pixels matrix to judge QR code primitive image judge black and white value, create original QR code image, then the QR code can be reverted and read in authorization equipment. The analysis results shows that the method can overcomes the security shortages of traditional QR code scanning technology, the cryptography QR code image can be resumed well with better security in military internet of things.
