Hello students.
00:01
Today we will discuss about this question.
00:03
In this question we are given that alice and bob use the diffel -hallmann key exchange technique with a common prime that is q that is equal to 23 and primitive root a that is equals to 5.
00:26
And here in part a, if bob has a public key, yb, that is equal to 5, that is equal to 5.
00:33
To 10, then we need to find what is the bob's private key yb.
00:41
And if in the part b, that is if alice has a public key ya that is equals to 8, then we need to find the shared key k with bob.
00:57
So here, first of all, we know that the common prime that is q that is equal to 23 and primitive root that that is alpha that is equals to 5.
01:08
So bob has a public key, yb is equals to 10, and we need to find the bob's private key, that is yb, xb, that is equals to question one.
01:20
So here, first of all, yb, that is equals to alpha, to xb, mode, q...
