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.


Scaffolding for our cooperative learning (CL) activity.

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

Before the keynote session,  8.30 a.m for RCEE 2020 Opening & Welcoming Address.
RCEE 2020 Penyertaan kertas kerja, penulis bersama Hazinah, Marina & Rashidah bertajuk : xxx.

Penggunaan aplikasi Whova sebagai medium komunikasi dan pengurusan bagi peserta dan pembentang. Menarik untuk digunapakai bagi CRC2021 nanti.


Selepas mesyuarat CAR, pengesahan markah, Audit Dalaman dan IAP Audit, masa untuk merancang bagi semester hadapan.

Terima kasih PM Dr Wan Nasir. Pandangan dari meja Pengerusi.

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.
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.



Benchmarks as Fast As Possible

A good introduction for benchmarks.


Best CPU Benchmark Software For Windows

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


First 5 Things I Do When Benchmarking

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



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.
