Answer:
Explanation:
The following code is written in Java. It is a method that calculates the square root of a number as requested. The method first checks with an IF statement if the parameter value is a positive number and then calculates the square root and prints it to the screen. Otherwise, it prints Number must not be negative. A test case has been provided in the main method and the output can be seen in the attached image below.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.print("Enter a number of type double to calculate square root:");
double num = in.nextDouble();
rootPositive(num);
}
public static void rootPositive(double num) {
if (num > 0) {
System.out.println(Math.sqrt(num));
} else {
System.out.println("Number must not be negative.");
}
}
}

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.
