Playfair Cipher: Encryption, Decryption, and Security Improvments | Report
| University | University of London (UOL) |
| Subject | Computer Science |
Assessment 1: Assignment
Weighting: 50%
Word Count: 2000 – 2500
Playfair cipher was a revolutionary approach of its times. It solved issues with existing approaches and ensured that regular frequency distribution of the English language would not work as a valid cryptanalysis approach. Playfair cipher only uses 25 alphabets in its key and this is one of its main limitations.
Consider that you are one of the developers at an organization. Your organization is committed to the use of Playfair cipher. They want to use this algorithm to encrypt all passwords that are being shared among systems. You are expected to ensure that you can make this algorithm work. Keep this in mind that Playfair cipher only uses alphabets whereas, a password should have symbols.
Do You Need Assignment of This Question
In this assignment, you are expected to explain the following:
- What is Playfair cipher
- How the conventional algorithm works
- Changes you propose to this algorithm
- Benefits that you gain from these changes
- Encryption and decryption based on this new variation
- What are the weaknesses of this new approach
Explain each step and make sure that you explain things in a way that your document can be used to explain the concept to a person new to the logic.
Note: Your assignment must be submitted as a single PDF report.
