Find the entropy of the second H (S2) extension and verify; then Find H(S4) and H(S11)?In an RSA system, the public key of a given user is e = 65, n = 2881. What is the private key of this user? Hint: First use trial-and-error to determine p and q; then use the extended Euclidean algorithm to find the multiplicative inverse of 31 modulo n.

- It is said that the set of pages in memory for n frames is always a subset of the set of pages in memory for n + 1 frames if the same series of accesses are made in the same order as before. Demonstrate LRU and OPT (recently) construct a hierarchy of algorithms.In the scenario above, calculate the average time to access a word, given.Say you are given a hash function that produces a 224-bit digest, along with a message digest d. Using random guessing, how long would you expect it to take to find a preimage? Say you are given a 224-bit hash function as in the previous question. Using random guessing, roughly how long should it take to find two messages with the same digest?
- When Bob wants to send Alice a message M on the Internet, he breaks M into n data packets, numbers the packets consecutively, and injects them into the network. When the packets arrive at Alice’s computer, they may be out of order, so Alice must assemble the sequence of n packets in order before she can be sure she has the entire message. Describe an efficient scheme for Alice to do this. What is the running time of this algorithm? From Data Structures and Algorithms C-7.56When the DFA minimization algorithm merges states p and q, then a) p and q are dead-end states b) p is distinguishable from q c) p and q are start states d) p is equivalent to q e) p and q are not reachable from the start stateIn the Bernstein-Vazirani algorithm, suppose a = 1001. Analyze each step of the protocol and write down the overall state after each step to show explicitly how the algorithm works to find a.
