3. For this task you are going to generate a key and use stream cipher.
(a) Use the quadratic residue pseudorandom generator (BBS)on the prime numbers
p and q of your choice, where 5000 < p, q< 9000, to generate the first five bits
of your key ko, k₁, k2, k3 and k₁.
(b) Generate a key sequence of length 40 by using the recurrence relation
In+5 = Xn+4 +In+2+In+1+xn (mod 2), n ≥0
where the initial values are the key generated in (a).
