Question

.3. users A and B use the Diffie-Hellman key,exchange technique with a common prime q=71and a primitive root as a=74)If user has private key xA=5,what isA's public key YA?5) If user B has private key XB=12, what isB's public key YB?6) What is the shared secret key?​

Answer 1

Answer:

a.If user A has private key XA=5, what is A’s public key YA?

Ya =7^5 mod 71 = 51

b.If user B has private key XB=12, what is B’s public key YB?

Yb = 7^12 mod 71 = 4

c.What is the shared secret key?

YK = 4^5 mod 71 = 30
