error-free perfect-secrecy systems Austell, Georgia

Since secret keys are valuable resources, how to efficiently use a key to achieve perfect secrecy is as important as how to generate a key.

Recently, Ho et al. Massey gave an information theoretic proof of this result and the proof did not require U and R to be independent.

Elec. Stott Prize for excellent research. By further assuming independence, we obtain a tighter lower bound, namely that the key entropy is not less than the logarithm of the message sample size in any cipher achieving perfect By adding an extra assumption that I(U;R) = 0, we show a tighter bound on H(R) in this talk.

We also consider the case that a perfect secrecy system is used multiple times. Grant Chinthani Uduwerelle Bookmark (what is this?) Computer Science > Information Theory Title: Error Free Perfect Secrecy Systems Authors: Siu-Wai Ho, Terence H. He worked as a postdoctoral research fellow at the University of Oslo, Norway, and Harvard University, until rejoining Philips Research UK in March 2008. Unlike the zero-delay setting where variable-length coding is traditionally used but might leak information on the source through the length of the codewords, in this setting, since delay is allowed, block

In this setting, we consider two models which differ by the ability of the eavesdropper to parse the bit-stream passing from the encoder to the legitimate decoder into separate messages. We also consider causal source coding with a fidelity criterion and side information at the decoder and the eavesdropper.

From June 2010 to June 2011, he worked as a postdoctoral fellow at UNIK - University Graduate Center, University of Oslo, Norway. This paper also illustrates that the lower bound only gives the minimum size of the pre-shared secret key.

The existence of a fundamental tradeoff between the expected key consumption and the number of channel uses for conveying a ciphertext is shown.

Massey gave an information theoretic proof of this result, however this proof does not require independence of the key and ciphertext. We derive bounds on the key rate and coding rate needed for perfect zero-delay secrecy. During 2006–2008, he was a Postdoctoral Research Fellow in the Department of Electrical Engineering, Princeton University, Princeton, NJ.
