1.The leftmost state bit is computed in the feedback path, which is the XOR sum of some of the flip-flop values in the previous clock period.

true or false

2.The flip-flop circuit will work only when the clock goes from low to high -leading edge.

true or false

3.A cipher is unconditionally secure if it can not be broken even with infinite computing resources.

true or false

4.PRNGs -pseudorandom number generators- produce sequences based on an initial seed value.

true or false

5.Random number generators are divided into two categories.

true or false

6.The XOR operation is comparable to modulo 2 subtraction.

true or false

7.Stream ciphers are compact and fast, making them ideal for applications with limited computational resources.

true or false

8.Electromagnetic waves have the ability to travel great distances.

true or false

9.In Stream Ciphers, encryption and decryption are two distinct functions.

true or false

10.Encryption and decryption functions are both simple additions modulo 2

true or false
