Jun 20, 2012 at 18:26 comment added Malice Oh yes i get it . It's same as the other equation if you reduce the first two terms
Jun 20, 2012 at 17:58 comment added Malice While expanding this Equation to a single round of DES, the Output of the function f is XORed with plain text . How does this equation we're talking about hold true because plain text is of random content but Matsui says this equation holds true $X_{2}[7,8,24,29]\bigoplus P_H[7,18,24,29]\bigoplus P_{L}[15]=K_{1}[22]$
Jun 20, 2012 at 17:33 comment added Malice Oh My mistake . I's counting bits starting from left handside and was getting a differnt expression,should start counting from right hand side . Spent hours trying to find this .A bucketfull of thanks

Corrected the mask, and explained more deeply how one can derive the linear expression.

Jun 20, 2012 at 12:07 comment added Malice And please note that it's $NS_{5}(16,15)$ not $NS_{5}(16,5)$ . Typo . I've edited the Question
Jun 20, 2012 at 12:04 comment added Malice Exactly . But I'm looking for is how did he manage the 1 round linear approximation from the $NS_{5}(16,15)$ equation . He did not describe that in the paper and nor can i find it anywhere on internet
