Here, We have successfully implemented the proposed methodology using DES (Data Encryption Standard)algorithm. The concept is enhanced by the transformation of meaningless to meaningful shares and the security is enhanced by encrypting the shares of the secret image by using DES. The tool that we ...

RSA(Rivest–Shamir–Adleman algorithm)算法是一种基于大数分解的困难性的非对称加密算法,它需要选择两个大素数作为私钥的一部分,然后计算出它们的乘积作为公钥的一部分(寻求两个大素数比较简单,而将它们的乘积进行因式分解却极其困难)。RSA 算法原理的详细介绍,可以参考这篇文章:你真的了解 RSA 加密算法吗? - 小傅...
This course aims to introduce students to the principles of cryptography and network security using the DES (Data Encryption Standard) encryption algorithm as an example. By the end of this course, students will be able to design their own DES-based encryption and decryption programs and ...
