Objectives: To learn about the AES encryption algorithm, digital certificates, EAP protocol, and WPA and WPA2 security Note: Be sure to include your work (i.e, brief explanations) in your answers to each of the questions (or, otherwise, points will be deducted if there is insufficient/inadequate amount of explanation in your submitted work). 1. (4 pts.) It is known that the inverse mix-column transformation used in AES encryption is OE OB OD 09 09 OE OB 0D OD 09 OE 0B OB 0D 09 OE that is, the product of the AES mix-column matrix and the AES inverse mix-column matrix equals the identity matrix as given in the below equation: 0E 0B 0D 091 102 03 01 011 [1 0 0 0 09 OE 0B OD 01 02 03 01 0 1 0 0 OD 09 OE OB 01 01 02 03 0 0 1 0 08 OD 09 0E] [03 01 01 02 0 0 0 1 In this question you are to show your work that verifies multiplying the 3rd row of the first matrix, by the 3rd column of the second matrix, will yield a value of 1 in the (3, 3)-entry of the resulting identity matrix. i.e.. calculate that (OD).101) 093.(03) e (oE.102) {OB)(01) = {01 } where the braces notation { } and product notation . are defined in the course notes and its referenced NIST publication NIST FIPS-197
