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.

Benchmark – COA’s Module 8

CPU & Hardware Performance Benchmarks

In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it.
A CPU benchmark (CPU benchmarking) is a series of tests designed to measure the performance of a computer or device CPU. A set of standards, or baseline measurements are used to compare the performance of different systems, using the same methods and circumstances.
There are available CPU benchmark software available and free for download. We may explore, try and experience it on our own computer.

 

I have found several interesting videos for you (specific to our COA’s class). You may go through the video one by one for better understanding.

 

MUST SEE VIDEO:

Benchmarks as Fast As Possible

A good introduction for benchmarks.

You may download the CPU-Z for a start, look through at your CPU and hardware specification.

Gamingg! Easy to relate right. However, benchmark is not limited to GPU, in our case we focus on CPU and hardware performance benchmarking.

 

EXTRA INFORMATION:

What’s the Difference Between a CPU and a GPU?

Hope the videos help us learning in exciting way and gain experience as much as we can with benchmarking.

Pelajar FC LI di Spain

Pagi ini dapat berita gembira. 4 pelajar FC selamat tiba di Spain. Mereka telah mendaftar dan akan menjalani Latihan Industri (LI) di Universidad Politécnica de Madrid.

Yazid & Arif
Ceria semuanya. Selamat berLI! – gambar kredit: Nurul Atifah.

Lebih teruja, Arif dan Yazid adalah pelajar di bawah PA.
