2)In the Needham-Schroder protocol is mesg 7 necessary? Explain.
3)What according to you is the most serious drawback of Kerbos style of authentication.
 a. State any 2 enhancement to kerb 5 over 4
4)Consider the EC y^2+xy = x^3 + a^4x^2+1.
 Over F24 represented by the irreducible trinomial x^4 + x + 1 where,
      a = (0010) element of F24
 ----> Examine whether the following pts are on EE
                         (a^6,a^9),(a^10,a^8),(a^12,a^8)
----> If the X coordinate of a pt is a^9, what is its y coordinate?
----> Compute (a^5,a^11)+(0,1)
----> (optional) write a program to determine the generator(s) of the group of points on the above Ecurve
----> Using EC version of E1 general encryption scheme as described in class,compute the encrypted versioin of the message =5
  (assume the rand # =8)

  PS : read 'a' as alpha
