An attacker has captured a target file that is encrypted with public key cryptography. Which of the attacks below is likely to be used to crack the target file?(A) Chosen plain-text attack
(B) Timing attack
(C) Replay attack
(D) Memory trade-off attack

Answers

Answer 1
Answer: D memory trade off attack
Answer 2
Answer:

Final answer:

The likely attack to crack the encrypted target file is a (D) Memory trade-off attack.

Explanation:

The attack that is likely to be used to crack the target file encrypted with public key cryptography is the Memory trade-off attack. This attack exploits the trade-off between memory usage and computation time. By precomputing and storing certain values in memory, an attacker can reduce the time required to crack the encryption.

In the case of public key cryptography, the attacker may try to crack the target file by precomputing and storing intermediate values from the decryption process. This allows them to quickly obtain the private key and decrypt the file.

4.2 Code Practice: Question 2Instructions
Write a loop that continually asks the user what pets the user has until the user enters rock, in which case the loop ends. It should acknowledge the user in the following format. For the first pet, it should say You have a dog with a total of 1 pet(s) if they enter dog, and so on.

Sample Run
What pet do you have? lemur
What pet do you have? parrot
What pet do you have? cat
What pet do you have? rock
------------
Sample Output
You have a lemur with a total of 1 pet(s)
You have a parrot with a total of 2 pet(s)
You have a cat with a total of 3 pet(s)

Answers

In python 3:

total = 0

while True:

   pet = input("What pet do you have? ")

   if pet == "rock":

       break

   total += 1

   print("You have a {} with a total of {} pet(s)".format(pet, total))

I hope this helps!

Answer:

pet = input(str("What pet do you have?"))

totalPets = 1

while(pet!="rock"):

  print("You have a " + str(pet) + " with a total of " + str(int(totalPets)) + " pet(s)")

  totalPets = totalPets+ 1

  pet = input(str("What pet do you have?"))

If your program throws an IndexOutOfRangeException, and the only available catch block catches an Exception, ______________________. A. the Exception catch block executes the Exception B. an IndexOutOfRangeException catch block is generated automatically the IndexOutOfRangeC. catch block is bypassedD. Exception is thrown to the operating system

Answers

Answer:

Option A is the correct answer for the above question.

Explanation:

The Index Out Of Range exception is a type of Run exception which is generated on run time. It means when any user executes the software or program, then that program gives some error on the execution time by some coding problem or some value problem.

So this type of exception can be handle by the Catch block which is also stated by the option A. Hence A is the correct answer but the other is not because:-

  • Option B states that this exception is generated by the catch block which is not correct.
  • Option C states that the catch block passes the exception which is also not the correct.
  • Option D states that the exception is passed for the operating system, but it is passed to the catch block only.
