Public-Key SteganographyAdded by Papergrl
Description:
In this work we introduce computational security conditions for public-key steganography similar to those introduced by Hopper, Langford and von Ahn for the private-key setting. We also give the first protocols for public-key steganography and steganographic key exchange that are provably secure under standard cryptographic assumptions. Additionally, in the random oracle model, we present a protocol that is secure against adversaries that have access to a decoding oracle (the steganographic equivalent of CCA-2 adversaries).
