(Solved) : Consider Following Key Exchange Protocol Alice Chooses Uniform K R 0 1 N Sends S Kr Bob B Q28150064 . . .
Consider the following key exchange protocol:
a) Alice chooses uniform k,r {0,1}n , and sends s = kr toBob.
b) Bob chooses uniform t {0,1}n , and sends u = st to Alice.
c) Alice computes w = ur and sends it to Bob.
d) Alice outputs “k” and Bob outputs “wt”.
Show that Alice and Bob output the same key.
Analyze the security of this scheme: Either prove its securityor show a concrete attack.
