INSTRUCTIONS TO CANDIDATES

ANSWER ALL QUESTIONS

Please write your code in R as an RMD file and submit your script and results for each of the following. 

1. Create an integer vector S with values from 1-5. Swap elements 1 and 4. [Hint: use the swap() function in package seqinr. ( 10 points)

2. Create a binary stream of bits for the string "Parabola". (10 points)

3. Create an initialized S vector for RC4. (10 points)

4. Create an initialized K vector for RC4. Assume that key is the UTF8 code of "Complete". (10 points)

5. Using the RC4 algorithm randomize S with 256 iterations. (10 points)

6. Using the RC4 algorithm generates a keystream of 128 bits starting with the output vector S in question 4. Assume that the key is "Complete". (15 points)

7. Implement RC4 for generating key streams. Your function should contain two parameters: a seed and a key length. (20 points)

8. Create an encryption function using RC4 that takes plain text and a key text as input and returns an encrypted stream of bits as output. (5 points)

9. Create a decryption function using RC4 that takes a cipher as a stream of bits and a key text as input and returns an encrypted stream of bits as output. (5 points)

10. Create a function that takes a binary stream as input and returns the corresponding text. (5 points)
