Instructions

• The submission file must be in the format of PDF.

• Submission of the PDF file must be made via the online submission system on  the course webpage.

Task 1 (3 marks)

What is the C.I.A.of security? Use examples to contrast security threats and attacks?

Task  2 (3 marks)

List 5 general design decisions that have to be made when constructing secure systems..

Task 3 (8 marks)

The smallest possible value for the modulus   n  for which the RSA algorithm works are

p =11, q =3   .  Use the most simplest example of RSA to do encryption. We would let

A  B   C   D  E   F   G  H  I    J    K  L   M  N  O  P   Q  R   S   T   U  V  W  X  Y  Z

2   3   4   5   6   7   8   9   10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

Thus the plaintext message “HELLOWORD” would be represented by the set of integers

{9, 6, 13,13, 16, 24, 16, 19, 13, 5 }   . Using the table above, please find ciphertext integers.
