On Resistance of DES to Related-Key Differential Cryptanalysis

Goce Jakimoski and Yvo Desmedt

Abstract

The key schedule of the Data Encryption Standard is analyzed, and it is shown that the properties of the permuted choice PC-2 transformation and the number of bits that are left shifted during the key generation are critical for the security of the algorithm. More precisely, we were able to mount a low complexity related-key attack on DES with slightly modified key schedule although no related-key attack is known for the original algorithm.
