Abstract

We introduce a problem setting which we call ``the freedom fighters' problem''. It subtly differs from the prisoners' problem. We propose a steganographic method that allows Alice and Bob to fool Wendy the warden in this setting. Their messages are hidden in encryption keys. The recipient has no prior knowledge of these keys, and has to cryptanalyze ciphertexts in order to recover them. We show an example of the protocol and give a partial security analysis.
