Efficient Public Key Steganography Secure Against Adaptively Chosen Stegotext Attacks
Tri Van Le and Kaoru Kurosawa
Abstract
We define the notion of adative chosen stegotext security. We then construct \emph{efficient} public key
steganographic schemes secure against adaptively chosen stegotext attacks, without resort to any special
existence assumption such as unbiased functions. This is the first time such a construction is
obtained. Not only our constructions are \emph{secure}, but also are essentially optimal and have
\emph{no error} decoding. We achieve this by applying a primitive called
