Capacity of the Additive Steganographic Channel Edics: 3-comm
نویسنده
چکیده
Many digital steganographic systems employ the capacity of an additive white Gaussian noise (WGN) channel as a performance metric. We present results that show that this capacity metric understates the capacity potential of these systems and propose a more accurate measure based on the arbitrary noise channel. This measure is compared to the capacity of the additive WGN channel and the performance of an actual image steganographic system.

Capacity Bounds and High-SNR Capacity of the Additive Exponential Noise Channel With Additive Exponential Interference
Communication in the presence of a priori known interference at the encoder has gained great interest because of its many practical applications. In this paper, additive exponential noise channel with additive exponential interference (AENC-AEI) known non-causally at the transmitter is introduced as a new variant of such communication scenarios. First, it is shown that the additive Gaussian ch...
متن کاملNew results on steganographic capacity
This paper extends recent results on steganographic capacity. We derive capacity expressions for perfectly-secure steganographic systems. The warden may be passive, or active using a memoryless attack channel, or active using an arbitrarily varying channel. Neither encoder nor decoder know which channel was selected by the warden. In some cases, the steganographic constraint does not result in ...
متن کاملEfficient Public Key Steganography Secure Against Adaptive Chosen Stegotext Attacks
We provide construction of steganographic schemes secure against adaptive chosen stegotext attacks. Our constructions achieve embedding rate equals to the Shannon entropy bound on steganographic channel capacity. Further the covertext distribution can be given as either an integrable probability function or as a random covertext sampler. We also introduce steganographic codes that are of intere...
متن کاملCompound Wiretap Channels
This paper considers the compound wiretap channel, which generalizes Wyner’s wiretap model to allow the channels to the (legitimate) receiver and to the eavesdropper to take a number of possible states. No matter which states occur, the transmitter guarantees that the receiver decodes its message and that the eavesdropper is kept in full ignorance about the message. The compound wiretap channel...
متن کاملNew results for Shannon capacity over generalized multipath fading channels with MRC diversity
In this article, we investigate the Shannon capacity for L-branch maximal combining ratio (MRC) over generalized multipath fading channel. We derive closed-form expressions of the maximal spectral efficiency over Rayleigh, Rician, Nakagami-m, and Weibull multipath fading channel under flat fading conditions. The results are expressed in terms of Meijer G-functions, which can be evaluated numeri...
