Answer #1

Solution:

Option-C : 11 is the correct answer

The keystream produced by A5/1 algorithm, is by 11. With the knowledge of only 11 bits of the known keystream, the attack algorithm is able to determine a set of 64-bit complete state candidates which may contain the key.

So, the keystream produced by A5/1 by 11.

Design a sequential circuit with two J-K flip-flops P and M and two inputs E and X. If E = 1, the circuit remains in the same state, regardless of the value of X. When E = 0 and X = 1, the circuit goes through the state transitions from 00 to 01 to 10 to 11, back to 00, and then repeats. When E = 0 and X = 0, the circuit goes through the state transitions from 00...
