Why can't you use Friedman's attack on block ciphers?

Computers and Technology

n200080 [17]2 years ago

4 0

Answer:

The Friedman's attack basically uses the same matrices in between the input of the blocks.

The similarities between the two given blocks is basically used to find the similar entries and hence, the deciphering is analyze the given pattern of the block in the system.

The input of the actual block pattern is encrypted into the different types of pattern in text of cipher. The basic parameters of the cipher block cannot be use for performing different types of attacks in the cipher without knowing the encrypted blocks.

To gain experience of using and combing different sorting algorithms: election sort, insertion sort, merge sort, and quick sort.

Answer:

Motivation? The search problem.

Sorting algorithms: insertion sort, shellsort, heapsort, mergesort, quicksort, bubblesort

At the very least, "general purpose" sorting algorithms require O(n log n) comparisons

Write multiple if statements. If car_year is 1969 or earlier, print "Few safety features." If 1970 or later, print "Probably has

Kazeer [188]

Answer:

import java.util.Scanner;

public class Hggg {

public static void main (String [] args) {

System.out.println("Enter the car make year");

Scanner in = new Scanner(System.in);

int car_year = in.nextInt();

if (car_year<1969){

System.out.println("Few safety features.");

}

else if (car_year>=1970 && car_year<1990){

System.out.println("Probably has seat belts.");

}

else if (car_year>=1990 && car_year<2000){

System.out.println("Probably has seat belts.");

System.out.println("Probably has antilock brakes.");

}

else if (car_year>=2000){

System.out.println("Probably has seat belts.");

System.out.println("Probably has antilock brakes.");

System.out.println("Probably has airbags.");

}

Explanation:

In this solution, multiple if statements have been used to accomplish each step. Observe that there are more than one print statements when year is greater than 1990 because the condition applied to year greater than 1970 holds true for every year greater than 1970 (1990, 2000 etc)

An automobile battery, when connected to a car radio, provides 12.5 V to the radio. When connected to a set of headlights, it pr

ladessa [460]

Base on the question, and in my further computation, the possible answers would be the following and I hope you are satisfied with my answer and feel free to ask for more.

- If you want to determine the Thevenin equivalent voltage and resistance without overloading the battery, then apply some known resistance

RLRL and measure the output voltage as VLVL. Measure the voltage without a load as VOCVOC. The voltage divider equation tells us that

VL=VOCRLRTH×RLVL=VOCRLRTH×RL

Solve for RTHRTH, and you know that VTH=VOCVTH=VOC.

Define a function CoordTransform() that transforms its first two input parameters xVal and yVal into two output parameters xValN

NISA [10]

Answer:

#include <iostream>

using namespace std;

void CoordTransform(int *ptr1, int *ptr2);

int main()

{

int xVal;

int yVal;

cout<<"please enter two valid integers";

cin>>xVal;

cin>>yVal;

CoordTransform(&xVal , &yVal);

int xValNew=xVal;

int yValNew=yVal;

cout<<xValNew<<yValNew;

return 0;

}

void CoordTransform(int *ptr1, int *ptr2)

{

int a = *ptr1;

*ptr1=(*ptr1+1)*2;

*ptr2=(*ptr2+1)*2;

}
