title = "Using data compression and randomisation to build an unconditionally secure short key cipher",
abstract = "We consider the problem of constructing an unconditionally secure cipher for the case when the key length is less than the length of the encrypted message. (Unconditional security means that a computationally unbounded adversary cannot obtain information about the encrypted message without the key.) In this article, we propose data compression and randomisation techniques combined with entropically-secure encryption for the case when message statistics are known. The resulting cipher can be used for encryption in such a way that the key length does not depend on the entropy or the length of the encrypted message; instead, it is determined by the required security level.",
