a) the body portion of the loop is not performed b) execution proceeds with the statement following the for state-ment c) both a and b d) none of the above

Answer the following statements true (T) or false (F)

1. A widely used technique for pseudorandom number generation is an algorithm known as the linear congruential method. 2. A cryptographically secure pseudorandom bit generator is defined as one that passes the least significant bit test. 3. The security of Blum, Blum, Shub is based on the difficulty of factoring n. 4. The stream cipher is similar to the one-time pad with a difference being that a one-time pad uses a pseudorandom number stream and a stream cipher uses a genuine random number stream. 5. The longer the keyword the more difficult the cryptanalysis.
