True Random Number Generation from Bioelectrical and Physical Signals

Algorithm 2

Sampler procedure.

Set the initial value: a₁=0.2, r=3.91, c₁=0

for  i=1 to n

a_i+1=a_ir(1- a_i)// a_i between 0-1

if  a_i ≥ 0.5  then

c_i=1

else

c_i=0

end if

end

j=1

for  i=1 to n

if  c_i==1  then

d_j= b_i //d_j: sampled number

j=j+1

end if

end
