Wi-Fi Protected Access (WPA) fixes critical vulnerabilities in the earlier wired equivalent privacy (WEP) standard. Understandin
Mars2501 [29]

Since Wi-Fi Protected Access (WPA) fixes critical vulnerabilities in the earlier wired equivalent privacy (WEP) standard, the attacks that is related to encrypted wireless packets is option A: IV attacks.

<h3>Describe an IV attack.</h3>

A wireless network attack is called an initialization vector (IV) attack. During transmission, it alters the IV of an encrypted wireless packet. One packet's plaintext can be utilized by an attacker to calculate the RC4 key stream produced by the IV employed.

Note that A binary vector used to initialize the encryption process for a plaintext block sequence in order to boost security by adding more cryptographic variance and to synchronize cryptographic hardware. The initialization vector is not required to be kept secret.

Answer:

See explaination

Explanation:

/File: ValidateCheckDigits.java

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileWriter;

import java.io.IOException;

import java.util.Scanner;

public class ValidateCheckDigits {

public static void main(String[] args) {

String fileName = "numbers.txt"; //input file name

String validFileName = "valid_numbers.txt"; // file name of the output file

//Open the input file for reading and output file for writing

try(Scanner fileScanner = new Scanner( new File(fileName));

BufferedWriter fileWriter = new BufferedWriter( new FileWriter(validFileName))) {

//Until we have lines to be read in the input file

while(fileScanner.hasNextLine()) {

//Read each line

String line = fileScanner.nextLine().trim();

//calculate the sum of first 5 digits

int sum = 0;

for(int i = 0; i < 5; i++) {

sum += Integer.parseInt( line.charAt(i) + "");

}

//Get the last digit

int lastDigit = Integer.parseInt(line.charAt(5)+"");

//Check if the remainder of the sum when divided by 10 is equal to last digit

if(sum%10 == lastDigit) {

//write the number in each line

fileWriter.write(line);

fileWriter.newLine();

System.out.println("Writing valid number to file: " + line);

}

}

System.out.println("Verifying valid numbers completed.");

} catch(IOException ex ) {

System.err.println("Error: Unable to read or write to the file. Check if the input file exists in the same directory.");

}

}

}
