Question: Explain why the cipher ek ( m ) = kLm and dk ( c ) m = kLc defined by XOR of bit strings is

Explain why the cipher
ek(m)= kLm and dk(c)m = kLc
defined by XOR of bit strings is not secure against a known plaintext attack. Demon- strate your attack by finding the private key used to encrypt the 16-bit cipher text c =1001010001010111 if you know that the corresponding plaintext is m =0010010000101100.
