Differential-linear weak key classes of idea
WebAbstract. This paper presents an analysis of the PES cipher in a similar setting as done by Daemen et al. at Crypto'93 for IDEA. The following results were obtained for 8.5 round PES: a linear weak-key class of size , two differential weak-key classes of size 2 , and two dierentiallinear weak-key classes of size 2 . WebFeb 11, 2016 · When two new differential characteristics in full-round of S-IDEA are used, yet the 4th round sub key is not required, the weak key class of 2¹³ will be 2²¹ and 2⁸ will be 2¹⁰.
