Brief

For this course work you are required to work in a group to design and implement a new encryption/decryption cipher - inspired by (but different to) existing ciphers of your choice, and produce an associated 3.000-4,000 word group report as detailed below.

Instructions for fulfilling the task:
• Describe a range of existing ciphers that you have studied and explain in detail those that helped inspire your cipher. Describe the weaknesses and strengths of each of those ciphers and explain why you decided to base the design of your own encryption/decryption cipher upon them.

• Fully specify and document your cipher and include the following:
- full explanation and detailed description of your encryption algorithm
- full explanation and detailed description of your decryption algorithm
- diagrammatically present the steps for both your encryption and decryption algorithm _step-by-step walkthrough examples of your encryption/decryption algorithms
- fully evaluate your cipher - including a detailed description of its strengths and weaknesses and justify which particular categories of application you think it would be best suited

• Implement your cipher for demonstration purposes use any programming language of your choice such as Python or Java (use of Excel spreadsheet is not recommended, but is an option), and ensure it is fully tested and evaluated.

• Assume that the users of your cipher are people who want to understand and learn how your cipher works; therefore ensure your implementation is user friendly and that it presents the outputs at each step of the detailed encryption/decryption process.
