ALA10: MODES OF OPERATION

There are five modes of block ciphers operation, called ECB, CBC, CFB, OFB, CTR.

Besides our notes, here we have five interesting related contents and research works that you may refer to:

Block Ciphers Encryption Modes & Use DES to Construct Stream Ciphers pg. 27-38 by Fabio Martignon LRI, France.

Evaluation Criteria (Modes of Operation) by Murat Kantarcioglu, UTD Dallas.

FIPS81 DES Modes of Operation by NIST.

Error Propagation in Various Cipher Block Modes by Karel Burda, BrnoUT Czech Republic.

Block Ciphers Modes of Operation by Tutorialspoint.

You may refer to other resources also for references.

1. Each group member must perform research individually: (1.5 marks)

  • Member 1 ECB & CTR
  • Member 2 CBC
  • Member 3 CFB
  • Member  4 OFB

Compare and discuss the advantage(s) and disadvantage(s) for each of properties:

  1. Identical plaintext
  2. Chaining dependencies
  3. Error propagation
  4. Efficiency

2. Then come out with ONE comparative table for modes of operation. (2 marks)

3. Then make an interesting Question and Answer based video. Maximum 5 minutes only. Publish on youtube. Share the link on the e-learning forum. (1.5 marks)

Explore & enjoy.

Due: Dec 2, 2024 Monday

PSM’s Important 3 to 8

FIGURES & TABLES

Importance 3: Figure caption must be below the figure.

Importance 4: Table caption must put on top of a table.

Importance 5: All figures and tables must be recited and explained in the text on the same page.

Importance 6: Separate table between pages, must has their own header and numbered.

Importance 7: Put frame (box) for figure

Importance 8: Every topic must start with text first; not figure or table.

Cryptography: Modes of Operation

Five modes of operation, called

  1. Electronic Codebook (ECB) – Group 1 & 6
  2. Cipher Block Chaining (CBC) – Group 2, 7 & 11
  3. Cipher Feedback (CFB) – Group 3, 8 & 12
  4. Output Feedback (OFB) – Group 4, 9 & 13
  5. Counter (CTR) – Group – 5 & 10

Each group may execute our CL activity based on modes of operation given.
