Consider a very simple symmetric block encryption algorithm in which 32-bits blocks of
plainext are encrypted using a 64-bit key. Encryption is defined as
C = (PāŠ•K0 ) āŠž K1

where C = ciphertext, K = secret key, K0 = leftmost 64 bits of K, K1 = rightmost 64 bits of K,
āŠ• = bitwise exclusive OR, and āŠž is addition mod 264
.

a) Show the decryption equation. That is, show the equation for P as a function of C, K0,
and K1.
b) Suppose and adversary has access to two sets of plaintexts and their corresponding
ciphertexts and wishes to determine K. We have the two equations:

C = (PāŠ•K0 ) āŠž K1 ; Cā€™

= (Pā€™āŠ•K0 ) āŠž K1

First, derive an equation in one unknown (e.g., K0). Is it possible to proceed further to
solve for K0?

Create a new dictionary called prices_stocks using {} format like the example below.

Ā 

prices_stocks={}

Put these values in your prices_stocks dictionary:

  • "banana": [4,5]
  • "apple": [2,2]
  • "orange": [1.5,2.5]
  • "pear": [3,4]

So the key of dictionary is name of item and value is a list (first element of that list is stock and second element is relevant price)

Loop through each key in prices_stocks, for each key, print out the key along with its price and stock information. Finally calculate how much you earn if you sold all of your products. Print the answer in the following format:

Ā 

Part-1:

Item: banana Stock: 4 Price: 5

Item: apple Stock: 2 Price: 2

Item: orange Stock: 1.5 Price: 2.5

Item: pear Stock: 3 Price: 4

If you sold all of your items you earn 39.75

Hi. You should write a Java program to meet the specification shown below. 

In this game(dice poker), the computer rolls two standard six-sided dice and you bet on the outcome. The outcome is the configuration of the numbers rolled (explanation below). The input/output should utilise a graphical user interface (input and message boxes).

 

1.1 Game flow

You start with some money in your bank. You play a number of rounds, where for each round you place a bet and the computer rolls the dice, checks results and modifies your bank balance. After certain conditions, the game ends and you're presented with some final information shown as a message box.

 

1.2 Placing bets

Before the computer rolls the dice, you can bet some money from your bank.

ˆ If the numbers are sequential (e.g. 1 and 2, 5 and 4, etc. Not 6 and 1), you earn double your bet.

ˆ If the numbers are identical (rolling doubles), you earn triple your bet.

ˆ Otherwise, you win nothing therefore you lose the amount of money you bet.

Before placing a bet, the computer should inform you of your current bank balance.

 

1.3 Starting Game- Game rules

When the game starts you are given £6 in your bank. Each bet costs £1 and you are allowed to make up to five bets before the game ends. The game will end if you run out of money, or you have no more attempts left (you made all five bets). At the end of the game, you will be told which of these conditions has ended the game.

 

1.4 Results display

Once the game has finished (all bets have been placed or you ran out of money) the computer will collate and display the results in a single message box, comprised by:

ˆ On row per bet, displaying your bet, the numbers rolled, the amount of money earned or lost for that bet.

ˆ One row at the end, displaying the amount of money that you have remaining in your bank at the end of the game.

 

1.5..Variable bet amount

Allow the user to change how much they would like to bet and change the amount you win accordingly. Allow bets between £1 and 4£ (integers only)

 

1.6.High score table

Create a high score table. The more money you have remaining in your bank at the end of the game the higher up the table you will be. In order to implement this, players will have to enter their name before they play. The high score table should be displayed as a separate message box after the results have been displayed at the end of the game(1.4)

Not1: Please use JoptionPane class instead of scanner class. 

Not2: Also If possible explain the description of your classes: what each does and how they relate to each other. And if possible, program should be extensible. E.g. Is it easy to change the number of dice? The number of rounds to play? The sides of the dice?Etc.
