A lot of encryption methods involving chaotic dynamics have been proposed in the literature since the 90's. Most of them consists in ``mixing'' the information to be hidden with a chaotic sequence. The recovering of the original information usually calls for reproducing, at the receiver side, the same chaotic sequence. The synchronization mechanism of the two chaotic sequences is known as {\em chaos synchronization}. In this paper, a connection between chaotic and conventional encryption is carried out with special emphasis concerning one of the most popular scheme, namely the chaotic message-embedding.
