WebThis paper presents a large collection of new weak-key classes for the IDEA cipher . The classes presented in this paper contain 2 -2 weak keys (as compared with 2 differential weak keys presented by Daemen at CRYPTO'93 and 2 differential-linear weak-keys presented by Hawkes at EUROCRYPT'98). The novelty of our approach is in the use of ... WebOct 22, 2014 · 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 .
