It is a method of encrypting alphabetic text by using a form of polyalphabetic substitution. A polyalphabetic cipher is any cipher based on substitution, ie using multiple substitution of alphabets. The encryption is done using a Vigenère table.
To encrypt a message using the Vigenère Cipher you choose a keyphrase. Then repeat this keyword over and over until it is the same length as the original text; this is referred to as a keystream.

Answer: Detailed
Explanation:
SDLC consist of 7 phases. They are:
1. Planning.
2. System analysis and requirement
3. Design:
4. Coding:
5. Testing:
6. Installation
7. Maintenance
Here we are talking of the third phase. In this phase it is the design phase which consist of high and low level design. Here the preliminary design is included in high level design where it describes the required hardware, software, network capabilities and the modelling of the interface. However the detailed design in low level design will implement the coding and will finding of any errors in the implemented design as described by the preliminary design.
