Encryption and Decryption

Question 1

Take a sample of Plain text, encrypt this plaintext step by step using AES, you must show each step how it has been done with all tables and codes, till you generate the Ciphertext. the reverse your work step by step till you generate the Plaintext

Your plaintext is:

“Here you can encrypt a block of bytes with a key using the popular Advanced Encryption Standard cipher. All the internal steps of the computation are shown, which can be helpful for anyone debugging their own AES implementation. In each of the 10/12/14 rounds, the sub-steps of SubBytes, ShiftRows, MixColumns, AddRoundKey, and key schedule are shown”

DO:

1) Encryption

2) Decryption

Question 2

SMB Encryption

Your department head has asked you to prepare a paper explaining SMB, how it would be used in your computing environment, how to secure it, and how it can be used to communicate and collaborate with partner organizations. (SLO 3c)

Your paper will be created using APA 6^th Edition formatting. Include the cover page, body, conclusion and reference page with at least two references outside of the assigned textbook. No abstract is necessary for this paper. (SLO 1a)
