Network Security: Single Round of DES Algorithm
Topics discussed:
1) Explanation of Round Function in DES.
2) Processing the Input 64 bits into the Output 64 bits through the Round Function.
3) Round Function Operations.
4) Introduction to the “F” Function or Mangler function.

Why there is an extra xor operation after the transposition?

naji

what happens in inverse initial permutation?

Very very thankful for your explaination ....

Are The values of the table fixed or changeable?

A lot of things here confuses me : In the key generation side there should be Left Half Key i-1 instead of Left Half i-1, also in the bottom there should be Left Half Key i, Right Half Key i instead of Left Half Key i-1, Right Half Key i-1. Also you didn't mention Permuted Choice 1 block that takes 64 bits and converts them to 56 bit which when divided into two parts (28 bits each) should be then left shifted, so your mention of 32 bit key inputs being left shift is also wrong. Also I didn't understand the Right Half i-1 block below the Transposition block because as far as I know we directly XOR the output of Transposition Block with left half of plain text so why did you mention that?

this is one of a damn complicated algorithms with actually no genius side or whatsoever in it
