I WILL GIVE DISLIKES !!! IF ANYTHING WRONG HAPPENS IN MY QUESTION, BETTER SKIP IT!!! "funksionet hash pr shifrat e bllokut
Madhsia e bllokut =8 bit
Madhsia e hashit =8 bit
Funksioni i enkriptimit: Ndani elsin n dy gjysma: LK dhe RK; Ndani tekstin e thjesht n dy gjysma: LT dhe RT; Pastaj ciphertext= LC||RC ku LC=LK XOR RT; dhe RC = RK XOR LT; ku LC, RC, LT dhe RT jan secili nga 4 bit; Teksti i thjesht dhe teksti shifror jan secili nga 8 bit. VH18
g(H)= nj varg 8-bitsh qsht i barabart me komplementin e biteve n H; Pr shembull, nse H=A3(Hexa)=10100011(binare); ather g(H)=01011100
H0= Hash fillestar =11001010
Jepet nj mesazh m: AB12(n Hexa);
1. Prcaktoni hash (n heksadecimal) t mesazhit M duke prdorur funksionin hash Matyas-Meyer-Oseas
2. Prcaktoni hash-in (n heksadecimal) t mesazhit M duke prdorur funksionin hash Davis-Meyer
3. Prcaktoni hash-in (n heksadecimal) t mesazhit M duke prdorur funksionin hash Migayuchi-Preneel"
