It only focuses on encryption and decryption, lacking mechanisms for data integrity verification or sender authentication. Summary In this chapter, we have learned about the affine cipher algorithm to encrypt an

In ...
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
This cipher is defined as: Letmbe a positive integer, andKconsist of all permutations of{1,...,m} For a key (permutation) , define: The encryption function The decryption function A small example, assuming m = 6, and the key is the permutation ...

Image Encryption and Image DecryptionIn this paper, we aim to investigate the security of multiple images based on affine hill cipher (AHC), fractional discrete cosine transform (FrDCT) and Arnold transform (AT). Three originalRGBimages are encoded as a singleRGBimage by first converting three...
The encryption machine takes the key Value and the XML input file and generate the encrypted text using Symmetric algorithm (Caesar cipher, Vigenere cipher &Affine cipher). The decryption Machine takes the encrypted file and key Value to generate the original XML file. These algorithms are ...
