Chosen ciphertext attack on a chaotic stream cipher

Abstract: This paper studies the security of a recently-proposed 3D chaotic self-synchronization stream cipher. Ac­cording to the chosen-ciphertext attack, a single key decipher algorithm is further ...

A Novel Dynamic Attack on Classical Ciphers Using an Attention-Based LSTM Encoder-Decoder Model

Abstract: Information security has become an intrinsic part of data communication. Cryptanalysis using deep learning-based methods to identify weaknesses in ciphers has not been thoroughly studied.
