olemus
plokkšifrite diferentsiaalne krüptoanalüüs, mille puhul
otsitakse mitte oodatavast suurema tõenäosusega erinevusi
(nagu tavaliselt), vaid vaheolekute võimatuid
(st nulltõenäosusega) erinevusi, kasutades neid
oletuste sõelumiseks (1998, mitu uurijat sõltumatult),
on andnud tulemusi paljude tuntud šifrite puhul
= cryptanalysis of block ciphers that exploits differences that are impossible (having probability 0) at some intermediate state of the cipher algorithm
