Secret Writing on Dirty Paper: A Deterministic View Academic Article uri icon

abstract

  • Recently, there has been a lot of success in using the deterministic approach to provide approximate characterization of Gaussian network capacity. In this paper, we take a deterministic view and revisit the problem of wiretap channel with side information. A precise characterization of the secrecy capacity is obtained for a linear deterministic model, which naturally suggests a coding scheme which we show to achieve the secrecy capacity of the degraded Gaussian model (dubbed as secret writing on dirty paper) to within half a bit. 2012 IEEE.
