Binary Hamming Code Write a program that has the following: 1. Let the program ask the user to enter the number parity-check sym- bols, m. 2. Let the program evaluate the code-length, n, the number of information- symbols, k. 3. Define a function that generates a systematic parity-check matrix H for such Hamming code. Let the H matrix differ each time the code runs

Vector Creation (creating equally spaced vectors) Write a script with commands to create the following vectors and assign to the indicated variable names. ■ Create an evenly-spaced row vector A with elements starting at 0 and ending at 50 with increments of 0.5. ▪ Create a row vector B with 80 evenly-spaced elements starting at 0 and ending at л/2. Your code should not include the following MATLAB functions or keywords: for, while. Hint: one line of your solution should start with A = and the other line of your solution should start with B =

Assume you have a hash table length of 29. Given the value 371, what index will the entry map to? 29 371 23 None of the above

9:05 Part 2: Encryption Details: description Objective: Develop a program that encrypts a plaintext file by XORing 128-bit blocks of the file with a key repeatedly until the entire file is encrypted. • The plaintext file will be a book from Project Gutenberg. Note: Done • The encryption method should use the XOR operation on the file, 128 bits at a time, with the key. • Each 128-bit block is XORed with the same key. • The program should work from the command line and accept three parameters: o The name of the key file Usage: o The name of the plaintext file o The desired name of the resulting ciphertext file This encryption method is not supposed to be secure.
