robema Design and implement simple stream cpher based on RCa You can als implement RC4 instead.) a. Design a simple Stream Cipher: a) Encrypt a byte (8 bits) at a time Key size: 256 bits. b) b. Implement a simple Stream Cipher: a) b) c) d) Show a demo by performing encryption on a plaintext: pick whatever plaintext you'd like to encrypt (e.g., this homework). Convert it to binary numbers for encryption Stream Key: this key is the input to your algorithm, not to encrypt plaintext. Set the key to all "1"s. Salt: generate random values to salt your key. For example, k'-k+salt. Remember to save the random values since you need them for decryption. Perform the decryption correspondingly c. Performance analysis: a) Encrypt 1000 times and record the computational time. i. Report your computer configurations (CPU clock speed, RAM, programming language used, etc.) ii. Feel free to change running iterations to get a good evaluation on computational time
