WebConsider a Diffie-Hellman scheme with a common prime q = 13, and a primitive root α = 7. a. Show that 7 is a primitive root of 13. b. If Alice has a public key Y A = 5, what is Alice’s private key X A? c. If Bob has a public key Y B = 12, what is the secret key shared with Alice? Answer: 7 is a primitive root modulo 13 if and only if 712≡ ... WebFirst, note that 5 is a primitive root mod 23, since its order mod 23 must divide φ(23) = 22, and so it must be 2, 11, or 22. First primitive root - Number theory and Group theory. Note …
