摘要
利用加解密算法DES和Shamir门限秘密共享算法,提出一种门限加密方案的实现,完成对文本和图像的加解密。通过对算法接口的分析,在算法理论的基础上,巧妙地将两种不同的信息安全算法有机结合在一起,并采用将像素值转换为二进制串的方式对图像进行加密,利用Java高级语言实现完整的可视化加解密过程。
Proposes a threshold encryption scheme based on DES encryption algorithm and Shamir threshold secret sharing to achieve the complete text and images on the encryption and decryption. On the basis of the theory of algorithms, two kinds of information security algorithm are creatively combined together through the analysis of interface of algorithms in order to encrypt and decrypt images, with the pixel value transformed into string of binary, and Java language helps achieve the complete visualization of the process of encryption and decryption.
