This project implements an Automated Caesar Cipher Decoder using machine learning. It predicts the Caesar cipher shift used in an encrypted message based on letter frequency analysis and then decrypts ...

Decrypt and Match Ciphertext to Plaintext This project implements a system to decrypt ciphertext and match it with its corresponding plaintext using machine learning techniques. The system takes ...

A known-plaintext attack (KPA) occurs when a hacker uses pairs of both encrypted and unencrypted data to figure out the encryption algorithm or key. In this attack, the hacker has access to both the ...

Abstract: With the explosion of Big Data in cloud environments, data owners tend to delegate the storage and computation to cloud servers. Since cloud servers are generally untrustworthy, data owners ...

Abstract: Existing methods for reversible data hiding in ciphertext binary images only involve one data hider to perform data embedding. When the data hider is attacked, the original binary image ...
