Efficient Public Key Steganography Secure Against Adaptively Chosen Stegotext Attacks

2009/4/10
We define the notion of adative chosen stegotext security.We then construct efficient public key steganographic schemes secure against adaptively chosen stegotext attacks, without resort to any specia...
Informally, a public-key steganography protocol allows two parties, who have never met or
exchanged a secret, to send hidden messages over a public channel so that an adversary cannot even
detect th...
A complexity-theoretic model for public-key steganography with active attacks is introduced. The
notion of steganographic security against adaptive chosen-covertext attacks (SS-CCA) and a relaxation

We construct efficient public key steganographic schemes, without resort to any special exis-
tence assumption such as unbiased functions. This is the first time such a construction is obtained. Not ...
