WebJul 24, 2015 · A differential cryptanalysis attack is a method of abusing pairs of plaintext and corresponding ciphertext to learn about the secret key that encrypted them, or, more precisely, to reduce the amount of time needed to find the key. It’s what is called a chosen plaintext attack; the attacker has access to plaintext and corresponding ciphertext.
