Describe basic network security and cryptographic

Question 1 For AES encryption technique assume the plain text is 128 bits and composed from your student id. For example if: 1. user ID=201 01 1995, the plaintext: 20 101199 5A BBCC DD 00 11 22 33 44 55 66 2. user ID- 201211005, the plain text: 20 12 11 00 5A BB CC DD 00 11 22 33 44 55 66 77 of 47 0c af 15 d9 b7 7f 71 e8 ad 67 The key K0= 29 59 d6 98 You are requested to provide the: 1. 2. The output of Pre round transformation (AddRoundKey) by using K0 The output of each stage in round 1^subBvtes, shittkows, and Mixcolumns) Hint: Hexadecima 00 04 12 14 12 04 12 00 0C 00 13 1 08 23 19 19 00 12 0C 08 04 04 00 23 inText M- 12 12 13 19 14 00 19 Question 1 For AES encryption technique assume the plain text is 128 bits and composed from your student id.
