Problems of the CASCADE Protocol and Renyi Entropy Reduction in Classical and Quantum Key Generation
Koichi Yamazaki, Ranjith Nair, Horace P. Yuen · arXiv (Cornell University) · 2007
It is shown that the interactive error correction protocol `CASCADE' should be analyzed taking the correlation between passes and finite length of sequence into account. Furthermore we mention some problems in quantifying the reduction of Renyi entropy by information announced during the error correction process.
