Dreaming of Keys: Introducing the Phantom Gradient Attack

Abstract

We introduce a new cryptanalytical attack, the phantom gradient attack. The phantom gradient attack is a key recovery attack that draws its foundations from machine learning and backpropagation. This paper provides the first building block to a full phantom gradient attack by showing that it is effective on simple cryptographic functions. We also exemplify how the attack could be extended to attack some of ASCONs’ permutations, the cryptosystem that won CAESAR the competition for authenticated encryption: security, applicability, and robustness.
