Hi,
I am searching attaks that work on the IDEA (complete 8 round) algorithm. I have found a paper entitled:New Weak-Key Classes of IDEA
by Alex Biryukov, Jorge Nakahara Jr, Bart Preneel, Joos Vandewalle.
I am familiar with the IDEA algo because I have implemented it in C as a part of my homework.
the problem is that I dont understand the Boomerang attak.
Here is the paper:
h++p://www.cosic.esat.kuleuven.be/publications/article-189.pdf
On page 4:
what is a differential pattern?
what is the definition of the reversed DELTA sign?
Is there anyone familiar with this attak who could explain it to me?
Thanks in advance
