Title: Efficient Steganography with Provable Security Guarantees

Abstract

Steganography is the art/science of hiding secret messages in other
messages, such that the secrets' very existence is concealed. Generally the
sender writes an innocuous message and then conceals a secret message on
the same piece of paper. Historical tricks include invisible inks, tiny pin
punctures on selected characters, minute differences between handwritten
characters, pencil marks on typewritten characters, grilles which cover
most of the message except for a few characters, and so on. This paper
discusses a new provably-secure steganographic encryption protocol built on
information theoretic constructions.
