- Suppose a train was supposed to start at station A, pause at stationsB, C, D, ... , Y, and finish at station Z. However, it did not arrive at Z. Suppose in yourfactory the piece of equipment or process labeled A makes part B work, which in turnmakes C, D, ... , and Z work. However, Z is not working. You want to find out why.What algorithm do you use? Think of other applications of this technique.Hi! This is not a graded question I just need it for my reviewer. Thanks! 2.Recall that a public-key cryptosystem consists of three functions: A key generator G, an encryption function E, and a decryption function D. Any user, say Alice (A), can use the key generator to generate a key pair (PKA, SKA), in which PKA is Alice’s public key, and SKA is her secret key; she can then publish her name and public key in a directory. Subsequently, anyone who wants to send a private message x to Alice can look up PKA in the directory, compute a ciphertext y ←− E(x, PKA), and send y to Alice over an open line. Only Alice can compute x ←− D(y, SKA), because only she knows the decryption key SKA that corresponds to encryption key PKA. Note that there is no need for a key-distribution center, as there is when one is using a symmetric-key cryptosystem, but there is a need for public-key directories. a) What is a public-key certificate? What is the problem with public-key directories that certificates…Execute and Check whether the following MATLAB code is correct or not in the command prompt.

- Given: NFA 1 q4 q3 q2 Using State Elimination Method, construct the regular expression equivalent to the given NFA. Add new start state q0 and new final state q1. Eliminate state q2 first, then state q3, then state q4, and state q5 last. Upon elimination of the four (4) states, the regular expression RE equivalent to the given NFA is Sample Answer: 10*(10)* NOTE: In your answer just use the exact number of parenthesis. That is, do not use extra parenthesis in your answer.Q4:- A fast computer is used to break a ciphertext (A) using columnar transposition cipher that needs 150 attempts, the speed of processor is 4 MIPS (million instructions per second), and each attempt needs 5 instructions. Another computer of speed 3 MIPS is used to break ciphertext (B) using Caesar Cipher that needs 110 attempts, and each attempt needs 4 instructions for ciphertext (B). Determine which ciphertext will be broken first (consider the worst case, i.e. the last attempt is the successful one), write your answer in details?Q3. Please consider the following mutual exclusion algorithm that uses the shared variables yı and y2 (initially both 0). Process P1: Process P2: while true do while true do ... noncritical section. .. yı := y2 + 1; wait until (v2 =0) V(yI < y2) ... critical section. .. yi:= 0; od ... noncritical section. .. y2:= yı + 1; wait until (yı = 0) V (y2 < yı) ... critical section. .. y2 := 0; od Please answer following questions: a) Give the program graph representations of both processes. (A pictorial representation suffices.) b) Give the reachable part of the transition system of P1 || P2 where yl<2 and y2 < 2. c) Describe an execution that shows that the entire transition system is infinite. d) Check whether the algorithm indeed ensures mutual exclusion. e) Check whether the algorithm never reaches a state in which both processes are mutually waiting for each other. f) Is it possible that a process that wants to enter the critical section has to wait ad infinitum?
- Solve the following puzzle by translating statements into logical expressions and reasoning fromthese expressions.Four friends have been identified as suspects for an unauthorized access into a computer system.They have made statements to the investigating authorities.1-Alice said Carlos did it.2-John said I did not do it.3-Carlos said Diana did it.4-Diana said Carlos lied when he said that I did it.If the authorities also know that exactly one of the four suspects is telling the truth, who didit?Answer the following questions given the figure (topic is about the A* algorithm):Legend:P=Player/Starting pointO=ObstacleG=Goal Given the figure, do the following:1. Mark each cell with its heuristic function h, using the "as the bird flies" distance. Use integers only.2. Show how the player (P) will reach the goal (G). For every cell planned for the player movement, show the updates f,g,h of its non-obstacle neighbor cells.A star configuration of a network represents its structure as a graph with an edge from a single, central node to each remaining node. A point-to-point configuration represents a network as a complete graph. Draw a picture of an example of each kind of configuration with four nodes, and use big-O notation to state the efficiency of adding or removing a given node in each type of configuration. You can assume for now that removing each edge is a constant-time operation. *Python
- Consider a memory system which only allows you to do sequential search. For example a read/write tapedrive. If you want to look for a file you have to search sequentially looking at the first file, then the secondfile and so on until you find the file. A reasonable strategy would be place the most recently retrieved fileat the front (imagine that the tape system can magically do this). This way the files that are accessed moreoften will be ”at the front” and require less searching time in the long run. Consider the case with only 3files A, B, and C.1. Let Xn denote the sequence of the memory system after the nth search. For example, if the files wereordered A and then B followed by C, then X0 = ABC. Enumerate the state space.2. If X0 = ABC, list all possible states of X1.3. If pA, pB, and pC = 1 − pA − pB are the probabilities with which files A, B, and C are accessed,respectively, determine the one-step state transition matrix.4. If pA = 0.6, pB = 0.10, pC = 0.3, determine the steady…For your initial post, identify a single algorithm that you use in your day to day life which involves repetition. As an example, washing each dish in a stack of dishes or a walk/don't walk sign switching from one mode to another after a set amount of time. Detail the steps of your algorithm in your post. As you detail the steps, make sure you break down each step fully. At a high level, explain how you would go about implementing the loop. Would you implement a while loop? A for loop? Would you make use of a "break statement?" Would your solution involve a nested loop?Create and put into action an iterative algorithm to address the Nonattacking Queens issue. Write a software to figure out how to arrange eight queens on an eight-by-eight checkerboard so that none of them are placed next to one another in a row, column, or diagonal. The chessboard is empty of any additional chess pieces.
