Somebody help me by giving correct answers for this difficult questions.

1. Determine the mode that is usually less prone to decryption between PRNG using OFB andPRNG using CTR.

2. Determine in Intel chips the most used and recent PRNGs.

3. Determine the initial value of the numbers k and v in an intel digital random no. generator given that the CTR mode uses a key K and V represents the initial vector.

4. Determine the length of the seed for AES- 192.

5. What is the term given to the output of the generator taking the reference from the stream ciphers.

6. Give examples of valid design parameters that should be considered when it comes to designing stream ciphers.

7. Justify the truth value of the generate function in that it precedes the update phase in CTR_DRBG.

8. Given 3DES, determine the seed length and provide an illustration or the answer.

9. Determine the length of the seed given that NIST CTR_DRBG.

10. Determine the number of keys that are to be used in the ANSI X9.17 PRNG.
