Abstract. A complexitytheoretic model for publickey steganography with active attacks is introduced. The notion of steganographic security against adaptive chosencovertext attacks (SSCCA) and a relaxation called steganographic security against publiclydetectable replayable adaptive chosencovertext attacks (SSPDRCCA) are formalized. These notions are closely related to CCAsecurity and PDRCCAsecurity for publickey cryptosystems. In particular, it is shown that any SS(PDR)CCA stegosystem is a (PDR)CCAsecure publickey cryptosystem and that an SSPDRCCA stegosystem for any covertext distribution with sufficiently large minentropy can be realized from any PDRCCAsecure publickey cryptosystem with pseudorandom ciphertexts. 1
