Consider a randomized public-key encryption scheme SE defined for messages that
are bitstrings of finite length, say n,(i.e. MsgSp ={0,1}n) that draws its randomness
from a finite space of size r.
Show that any notion of a perfectly secret public key encryption is impossible i.e. a
computationally unbounded adversary can decrypt any ciphertext c with probability
1.
