成果介绍

本发明属于图像加密技术领域，公开了一种身份认证方法，该方法包括：以螺旋相位板为切向傅里叶变换加密算法中的加密密钥，采用切向傅里叶变换加密算法对M幅图像中的每一幅图像进行加密处理，对应生成M个振幅白噪声和M组相位密钥组，将M个振幅白噪声线性叠加得到振幅白噪声集，将M组相位密钥组分别按照叠加算法进行叠加复用获得不同等级的认证相位密钥组，使拥有不同等级的认证相位密钥组的用户具有不同级别的系统资源访问权限，实现多图像和多级别的认证，增强系统安全。同时，该方法采用的螺旋相位板的密钥不是公开的密钥，在不知道密钥的情况下，很难识别出原始的明文信息，有效地避免认证相位密钥被伪造的风险，信息的安全得到保障。
