采用Shamir门限秘密分享方案,提出一种带有认证功能的图像可视加密算法。该算法主要思想是,先将二值秘密图像分块得到数据,然后使用Shamir的门限秘密共享方案得到子秘密数据,同时用SM2签名算法对秘密图像进行签名,并将分享数据和签名信息嵌入载体图像。还原时需要指定张数的子秘密图像进行信息的提取、还原与认证。仿真实验结果表明,该秘密图像分享方案提高了秘密图像存储与传输的安全性。
An image visualization encryption algorithm with authentication function by using Shamir scheme was proposed.The main idea of this algorithm is to obtain the data by segmenting the binary secret image into blocks.Then
Shamir scheme was used to obtain the sub-secret data and simultaneously sign the secret image with the SM2 signature algorithm.And it would embed the shared data and signature information into carrier images.When the restoration is required
a specified number of sub-secret images are required for information extraction
restoration and authentication.The simulation experiment of the scheme shows that the secret image sharing scheme improves the security of secret image storage and transmission.
