Good ratings for good job. Thanks!

1.Describe the Runs Test. Explain the meaning.

2.What is the term used to refer to the test that is used to determine whether the number of ones and zeroes in a sequence is approximately equal as in a truly random o/p.

3.Determine the size of the keys in a stream cipher key which is also equal to 128 bits.

4.Determine between PRF, TRNG and PRNG the one that has the lowest bitrate.

5.The main reason for the development of RC4 was to serve the purpose of generating random bits so as to act as a PRNG. Determine the truth value in this statement.

6.Determine the Maurer's universal test for statistics.

7.The main property of backward unpredictability is that it makes it difficult to determine the seed from any previous knowledge of the bits sequence. True or false?

8.Given that the seed is not known, forward unpredictability is used to refer to the next output bit in the sequence and it should be unpredictable. True or false?

9.Determine the name given to TRNGs which take in an output.

10.Given TRNGs and PRNGs, determine which one between the two cannot be used in the case where stream ciphers are involved.
