Decryption of Affine CipherWhen we've to decipher a ciphertext translated with the help of the Affine Cipher encryption system, we will have to do the contrary process of what we've done to cipher it. The first step is to convert each ciphertext letter back into its number value, just ...
仿射密码加密,解密 C++实现仿射密码加密解密以及仿射密码的爆破(C++ implementation of affine cipher encryption and decryption)
The algorithm first scrambles pixels position by using Lorenz chaos sequence, and then introduces the affine cipher of classical cryptograph to diffuse and confuse pixel values. Theoretical analysis and experimental results show that the algorithm has high sensitivity keys, better security of encryption,...
Due to the linearity of the Hill cipher, it is vulnerable against smaller key spaces. Furthermore, the same weaker secret key is used to generated the self-invertible matrix, and is used for both encryption and decryption. In this work, we examine the security of the scheme in [7] and ...
C++ Header only string obfuscator library using metaprogramming. Affine Cipher technique is used for encryption and decryption. - Litch666/String-Obfuscator-In-Compile-Time
Likewise, in decryption as well, since decryption is performed using a multiple-affine key system automatically rewritten each time when the number of use times reaches a predetermined number, a third party cannot reproduce the multiple-affine key system and therefore cannot decipher a cipher text....
In this scenario, a robust image encryption technique over open network has grasped a great deal of attention. In this paper to meet this challenge, we have established a new multi-layer robust color image encryption using random matrix affine cipher (RMAC), reality preserving two dimensional ...
Likewise, in decryption as well, since decryption is performed using a multiple-affine key system automatically rewritten each time when the number of use times reaches a predetermined number, a third party cannot reproduce the multiple-affine key system and therefore cannot decipher a cipher text....

To overcome such security issues, cryptography, steganography and watermarking methods are utilized ...
This paper develops a public key cryptosystem using Affine Hill Cipher. The proposed method increases the security of the system because it involves two or more digital signatures under modulation of prime number. to as encryption and reverse process is known as decryption. Cryptanalysis involves an...
