2016/4/26
The log-likelihood ratio (LLR) test statistic has been proposed in the literature for performing statistical analysis of attacks on block ciphers. A limitation of the LLR test statistic is that its ap...

In this paper we study the long standing problem of information extraction
from multiple linear approximations. We develop a formal statistical framework for block
cipher attacks based on this techn...
