Problem: Pseudorandom number generators are at the heart of stream ciphers. They take a seed value and expand it into an open-ended amount of pseudorandom data. How should the seed value be chosen so as to make the resulting stream cipher secure?
In your answer, please be sure to define all terms, especially these: seed value, pseudorandom, and secure. Make it clear what happens if the seed is selected correctly, and what happens if it is not.
