(1 point) Note: The notation from this problem is from Understanding Cryptography by Paar and Pelzl.A LFSR with m internal state bits is said to be of maximal length if any seed state (except 0) produces anoutput stream which is periodic with the maximal period 2m 1. Recall that a primitive polynomialcorresponds to a maximum length LFSR. Primitive polynomials are a special case of irreducible polynomials(roughly, polynomials that do not factor). In the context of LFSRs, a polynomial is irreducible if every seedstate (except zero) gives an LFSR with the same period (though the period length may not be maximal). Wewill call a polynomial with neither of these properties composite.Classify the following polynomials as either primitive, irreducible, or composite by writing either P, I or C in thecorresponding answer blank below.×4a) x + x3 + x² + 14b) x + x² + 1c) x 1 + x ³ + x² + x¹ +1d) x + x³ +1

RC4 has a secret internal state which is a permutation of all the possible values of the vector S and the two indices i and j a. Using a straightforward scheme to store the internal state, how many bits are used? b. Suppose we think of it from the point of view of how much information is represented by the state. In that case, we need to determine how may different states there are, then take the log to the base 2 to find out how many bits of information this represents. Using this approach, how many bits would be needed to represent the state?

Computer Networks The book demonstrated that a poisoned reverse will prevent the count-to-infinity problem caused when there is a loop involving three directly connected nodes. However, other loops are possible. Will the poisoned reverse solve the general case count-to-infinity problem encountered by Bellman-Ford? Yes, the poisoned reverse will prevent a node from offering a path that includes preceding nodes in the loop. It will not, preceding nodes may still be used in the computation of the distance vector offered by a given node.

The 1988 version of X.509 lists properties that RSA keys must satisfy to be secure, given current knowledge about the difficulty of factoring large numbers. The discus- sion concludes with a constraint on the public exponent and the modulus n: It must be ensured that e > log₂(n) to prevent attack by taking the eth root mod n to disclose the plaintext. Although the constraint is correct, the reason given for requiring it is incorrect. What is wrong with the reason given and what is the correct reason?
Expanding randomness. Alice wants to implement AES in CTRmode on a small IoT device that doesn’t have a good source of randomness.She has observed that, in practice, she can obtain four randombits for each encryption. To produce the 64 bits of nonce needed foreach encryption, she proceeds as follows. She takes the SHA256 of thefour random bits. Then she uses the first 64 bits of the SHA256 outputas the nonce. Is this method secure? Explain your reasoning. (Hint:consider what happens if the adversary tries to guess the nonce. Howmany possibilities are there? Would guessing the nonce help themdecrypt the message?)
