Calculating brute force attack
How long will take for a computer that can test 1000 billion (10^12) keys per second, to carry out a brute force attack in an encrypted file using 128-bit -AES. Your answer should be in years using scientific notation correct to 2 significant figures and you may assume that "one year" is 3.2 x 10^7 seconds.
Can I have this with an explanation of the steps taken?

Brute force attack
What is the maximum amount of time that it would take a computer that can test 1000 billion (1012) keys per second to carry out a brute-force attack on a file encrypted using 128-bit AES? Give your answer in years, using scientific notation, correct to 2 significant figures.
128-bit AES calculation
What is the maximum amount of time that it would take a computer that can test 1000 billion (1012) keys per second to carry out a brute-force attack on a file encrypted using 128-bit AES? Give your answer in years, using scientific notation, correct to 2 significant figures.From the question above, Could you please explain the step by step of the following: 2^128 / 10^12 x 3.2 x 10^7 = 2^128 / 10^18 x 32 (how the 10^18 and 32 appeared...

Assume that we are planning to decrypt the cyphertext which was encrypted with DES encryption. We are using an ordinary household computer with 2GHz processor. Estimate the amount of time necessary to crack DES by testing all 56-bit possible keys. Also estimate the similar time for AES encryption with 128-bit key. (Assume that machine takes 100 cycles per brute force against a single key)

Explain your answer Problem 3 10 points] A 4-bit long message was encrypted using one-time pad to yield a cipher-text “1010” Assuming the message space consists of all 4-bit long messages, what is the probability that the corresponding plaintext was “1001”? Explain your answer. Problem 4 Assume we perform a...

You have in your possession a wireless emulator the size of a 6" cube (i.e., 6" x 6" x 6) with a weight of less than 5 pounds which you can take to a parking lot containing 1,000 new cars. Each car has a four-digit wireless door key (between "0000" and "9999 using wireless symbols) as well as a three-digit engine key (between "000" and...
