2.9. Given is a stream cipher which uses a single LFSR as key stream generator. The LFSR has a degree of 256. 1. How many plaintext/ciphertext bit pairs are needed to launch a successful attack? 2. Describe all steps of the attack in detail and develop the formulae that need to be solved. 3. What is the key in this system? Why doesn’t it make sense to use the initial contents of the LFSR as the key or as part of the key

Describe in pseudocode an algorithm that given an integer n and a linked list of elements increases the linked list by a factor of n by replacing each element in the original list with n copies of that element. for example, if l: [18, 7, 4, 24, 11] and n = 3 the resulting list should be l: [18, 18, 18, 7, 7, 7, 4, 4, 4, 24, 24, 24, 11, 11, 11]. if the value of n is less than or equal to 0, the list should be empty after the call. what’s the running time of your algorithm?
