Q11.

Bob selects E67(2, 3) as the elliptic curve over GF(p). He selects e1 = (2, 22) and d = 4. Then he calculates e2 = d × e1 .What is the value of e2?

(23,49)

(16,55)

(12,19)

(13,45)

Discuss

Answer: (d).(13,45)

Q12.

Bob selects E67(2, 3) as the elliptic curve over GF(p). He selects e1 = (2, 22) and d = 4. Then he calculates e2 = d × e1 and the publicly announces the tuple (E, e1, e2). Now, Alice wants to send the plaintext P = (24, 26) to Bob and she selects r = 2. What are C1 and C2?

C1=(35,1) ; C2 =(21,44)

C1=(44,21) ; C2 =(1,35)

C1=(44,21) ; C2 =(44,21)

C1=(21,44); C2 =(35,1)

Discuss

Answer: (a).C1=(35,1) ; C2 =(21,44)
