Question 4
a) Demonstrate with the use of simple python line codes on how to: (i) encrypt
and (ii) decrypt a sensitive message
b)
The statement: “While some breaches are accidental, many are intentional”. It is
however very challenging sometimes to establish in investigation processes about
accidental and intentional breaches. As an assumed security officer of your
company explain some outlines that properly classify accidental security and
intentional.
c)
In determining if your computer is vulnerable to an Internet or network attack,
you could use an online security service, which is a Web site that evaluates your
computer to check for Internet and e-mail vulnerabilities. What would be the
reaction of a company to use online network service solution for vulnerability
checks.

- Question 13 sum .Which of the following statements is the closest to reality? A. There is mathematical proof that modern cryptographic systems cannot be broken. B. Messages encrypted with modern cryptographic systems may be broken given enough . time. C. An attacker can easily decrypt and read cipher text if they know which cryptographic system was used to encrypt the message. D. All of the statements are equally true. Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this lineb.What is the maximum amount of time that it would take a computer that can test keys per second to carry out a brute-force attack on a file encrypted using 256-bit AES? Give your answer in seconds and years, using scientific notation, correct to 2 significant figures. You may assume a year is seconds and you may use a calculator to help work out the answer. Show all your working clearly in a way that will help your tutor understand how you arrived at your answer.Because of recent developments in cryptanalysis, there has been a rise in the use of quantum computing. Reviewing and comprehending three to five current papers on the use of quantum computing to the process of password cracking is recommended. It would be reasonable to do a research of one to two pages on the positive and negative aspects of quantum computing.
- 8. A security system is used to encrypt the password of a cryptocurrency wallet (crypto wallet) and generate 10 different codes that the owner of the wallet can copy on 10 papers that he will hide with great care. So if a thief finds 1 of these hidden papers, he will not be able to unlock the wallet. Indeed it would be necessary to have at least 6 (any 6) codes to reconstitute the secret passphrase and unlock the wallet. How is it possible ?Question # 1: Use the Affine cipher method to encrypt the following plaintext:Summer Term CompletedKey pair (K1, K2) = (5, 3) Remember: i need a Mathematics solution not computer program You must show all the steps of your workIs it feasible to encrypt both the data and the connection from beginning to end? What are the advantages of doing this? Please provide an example of a situation in which the use of encryption might be advantageous.
- Can you explain more about this question 1. How many passes should you do if the keys were all different? Answer here: Minimum 200 words where you discuss the specific implications (i.e., I don’t want a hunch or opinion, base it on facts…maybe use math). I’m understanding that any modern cipher should be secure with one pass. We should have only one pass because any modern cipher should be secure with one pass. The ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it. This process prevents the loss of sensitive information via hacking.so, we do have only one pass.Is it feasible to encrypt the connection and data end-to-end? What is the advantage? Describe a situation in which all encryption approaches are beneficial.The Caesar Cipher Algorithm was introduced in Week #1. Encryption is the act of encoding a message with the intent of allowing only authorized people the knowledge of how to read that message. An encrypted message can be decoded, allowing the secured content to be read after decryption. Recall that the Caesar Cipher uses alphabets as the primary source of information but shifted a certain number of letters to the left or right as a key to create the encrypted data. The Caesar Cipher is easily hacked because of the simple technique used to build the key that encrypts and decrypts the data. In this lab, the key is the number of alphabets shifted, and the direction is always toward the increasing alphabetical order. This provides 26 ways of encrypting a message and therefore makes it easier to be hacked by guessing the key within the range of 0 - 25. Write the function caesar_hack( ) that takes three parameters: a Caesar Cipher encrypted message, an alphabet list, and the original…

The password is alphanumeric and case-sensitive. Show your calculation steps and provide an explanation of how you arrived at the answer. Why is the entropy an approximation and not a true reflection of the strength of a password?A. In one of his cases, Sherlock Holmes was confronted with the following message: Cz sio wuh vlyue nbcm gymmuay, nbyh sio ohxylmniix Wuymul wcjbyl! Although Watson was puzzled, Holmes was immediately able to deduce the type of cipher. Can you? B. Show that DES decryption is, in fact, the inverse of DES encryption.
