### Paper: Efficient Public Key Steganography Secure Against Adaptively Chosen Stegotext Attacks

Authors: Tri Van Le Kaoru Kurosawa URL: http://eprint.iacr.org/2003/244 Search ePrint Search Google 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 $\ch{P}$-codes.
