Using Transformers (multi head attention encoder - decoder) to classify encrypted ciphertext with no additional context

Vectorized each input sentence by encoding each word in a sentence with its corresponding frequency rank; used top 20,000 words as vocabulary size. Neural Word Embeddings were used (Keras Embedding ...

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 ...

Ciphertext Mapping Method based on Gray Code in Quantum Noise Stream Cipher

Abstract: A ciphertext mapping method based on Gray code is proposed to improve the security of quantum noise stream cipher (QNSC). The experiment is conducted in 1024 × 1024 -quadrature amplitude ...

How do you measure the difficulty and success rate of a ciphertext-only attack?

A ciphertext-only attack is a type of cryptanalysis where the attacker only has access to the encrypted message and tries to recover the original plaintext or the key used to encrypt it. This is one ...
