“Specify in the correct order (from top to bottom), which Pseudo Random Number Generation schemes are represented here?
i)
m = [ n/outlen] w_o = V
W = the null string
For i = 1 to m
w_i = MAC(K,w_i-1)
W = W || wi
Return leftmost n bits of W
ii)
m = [n/outlen] W = the null string
For i = 1 to m
w_i = MAC(K,V || i)
W = W || w_i
Return leftmost n bits of W
iii)
m = [n/outlen] A(0) = V
W = the null string
For I = 1 to m
A(i) = MAC (K,A(i-1))
w_i = MAC (K, a(I) || v)
W = W || w_i
Return leftmost n bits of W”
