Authentication protocols are usually designed and configured to create a number that will be used only once, so as to prevent replay attacks in a computer network. Thus, this number is called a <u>nonce</u>.

Authentication work based on the principle of strategically matching an incoming request from an end user or electronic device to a set of uniquely defined credentials.

In an access control list (ACL), authentication and authorization is used to ensure an end user is truly who he or she claims to be, as well as confirming that an electronic device is valid through the process of verification.

In Cybersecurity, authentication protocols are usually designed and configured to create a nonce, which can be used only once, so as to prevent replay attacks in a computer network.

In conclusion, a nonce is used prevent replay attacks in a computer network because the number created by an authentication protocol can be used only once.

Margaret [11]

Answer:

The following are the program in the C++ Programming Language:

#include <iostream> //header file

#include <string> //header file

#include <vector> //header file

//name space

using namespace std;

//main function

int main() {

vector<string> word; //set variable

vector<int> c; //set variable

int s, counts = 0; //set variable

string strng; //set variable

cout<<"Enter the size of string: "; //print message

cin >> s; //get input

cout<<"Enter the string: "; //print message

for(int i = 0; i < s; ++i) { //set for loop

cin >> strng; //get input

word.push_back(strng);

}

for(int i = 0; i < s; ++i) { //set for loop

counts = 0;

for(int j = 0;j<word.size();j++){ //set for loop

if(word[j] == word[i]){ //set if statement

counts++; //increament in counts

}

c.push_back(counts);

}

for(int i = 0; i < s; ++i) {

cout << word[i] << " " << c[i] << endl;//print result

}

return 0;

}

<u>Output</u>:

Enter the size of string: 2

Enter the string: hello sir

hello 1

sir 1

Explanation:

Here, we define three header files <iostream>, <String>, <vector> and namespace "std" after that we define main() method inside it.

Then, we set two vector type variables first one is string variable "word" and the second one is integer variable "c".
Then we set two integer variable "s" and "counts" and variable "counts" assign to 0.
Then, we get input from the user in variable "s" for the length of the loop.
Then, we set for the loop inside it, we get input in the variable "strng" from the user.
Then, we set the for loop for count the string repetition if any word comes again in the string then the value of count will increase.
Finally, we set for a loop to print the result.

Write a method that finds the cheapest name of apples, and returns back a String stating what the apple name is and how much it

Korolek [52]

The question is incomplete! Complete question along with answer and step by step explanation is provided below.

Question:

Two arrays are given:

String apples[] = {"HoneyCrisp", "DeliciousRed", "Gala", "McIntosh", "GrannySmith"};

double prices[] = {4.50, 3.10, 2.45, 1.50, 1.20};

Write a method that finds the cheapest name of apples, and returns back a String stating what the apple name is and how much it costs. The method should take two arrays as two parameters (you do not need to make a two dimensional array out of these arrays).

Answer:

The complete java code along with the output is prrovided below.

Java Code:

public class ApplesCheap

{

public static String Cheapest(String apples[], double prices[])

{

int temp = 0;

for (int i = 0; i < apples.length; i++)

{

if (prices[i] < prices[temp])

{

temp = i;

}

return apples[temp];

}

public static void main(String[] args)

{

// define the array of apple names and their prices

String apples[] = {"HoneyCrisp", "DeliciousRed", "Gala", "McIntosh", "GrannySmith"};

double prices[] = {4.50, 3.10, 2.45, 1.50, 1.20};

// print the cheapest apple by calling the function Cheapest

System.out.println("The cheapest apple is: " + Cheapest(apples, prices));

}

Output:

The cheapest apple is: GrannySmith
