Suppose that Alice's RSA parameters are m_A=91, e_A=7, and d_A=31. And suppose that Bob's RSA modulus is m_B=187.

a)If Bob's public exponent is e_B=13 and Alice wants to encrypt the message signature pair (x, delta)=(70,21), calculate her encrypted pair.

b)If Bob's private exponent is d_B=37 and he receives the enciphered message signature pair (11,69), what are the original plaintext and signature? Is this a valid message signature pair?
