Suppose Alice downloads a buggy browser that implements TLS incorrectly. The TLS specification says that, during the handshake, the browser should send a random 256-bit number RB. Instead of picking RB randomly the browser always sends all zeros. Describe an attack that is possible against this buggy browser and how to update the browser so that this attack is no longer feasible.

Answers

Answer 1

Solution :

It is given that Alice downloads the buggy browser which implements a TLS incorrectly. The specification of a TLS states that during a handshake, the browser sends a 256 bit number of RB randomly.

So in this case, a man-n-the-middle attack is possible. It can compromise the confidentiality of Alice. Updating the browser by visiting the website and checking its latest version of the browser or installing some other browser which has a more trust in the market for its security features.

What are
the rules for giving
variable name ?​

Answers

Answer:

Rules for naming variables:

- Variable names in Visual C++ can range from 1 to 255 characters. To make variable names portable to other environments stay within a 1 to 31 character range.

- All variable names must begin with a letter of the alphabet or an underscore ( _ ).  For beginning programmers, it may be easier to begin all variable names with a letter of the alphabet.

- After the first initial letter, variable names can also contain letters and numbers.  No spaces or special characters, however, are allowed.

- Uppercase characters are distinct from lowercase characters.  Using all uppercase letters is used primarily to identify constant variables.  

- You cannot use a C++ keyword (reserved word) as a variable name.

Write a template that accepts an argument and returns its absolute value. The absolute entered by the user, then return the total. The argument sent into the function should be the number of values the function is to read. Test the template in a simple driver program that sends values of various types as arguments and displays the results.

Answers

Answer:

In python:

The template/function is as follows:

def absval(value):

   return abs(value)

Explanation:

This defines the function

def absval(value):

This returns the absolute value of the argument using the abs() function

   return abs(value)

To call the function from main, you may use:

print(absval(-4))

my code get an input of 1900 and it should output not a leap year but it fails first line of code. It should output not a Leap any number with 1500 not divisble by 4 with/out a remainder should output (not a leap year. )


input_year = int(input())

if input_year % 4 == 0: #fails on this step, 1900 should be false
print(input_year, "- is Leap Year")

elif input_year % 100 == 0:
print(input_year, "- leap year")

elif input_year % 400 ==0:
print(input_year, "is a leap year")

else:
print(input_year, "- not a leap year")

Answers

Answer:

Explanation:

The code does not fail on the first step since 1900 divided by 4 is actually 475 and has no remainder, meaning that it should return True. The code won't work because the if statements need to be nested in a different format. The correct algorithm would be the following, which can also be seen in the picture attached below that if we input 1900 it would output is not a leap year as it fails on the division by 400 which gives a remainder of 0.75

input_year = int(input())

if input_year % 4 == 0:

   if input_year % 100 == 0:

       if input_year % 400 == 0:

           print(input_year, "is a leap year")

       else:

           print(input_year, "- not a leap year")

   else:

       print(input_year, "is a leap year")

else:

   print(input_year, "- not a leap year")

A new office need 16 computer Tables.If a computer tables costs 2,671.How much is needed to purchase 16 computer tables.​

Answers

Answer:

The total amount needed to purchase the 16 computer tables is 42,736

Explanation:

Given;

Total number of computer tables needed in the new office, n = 16

cost of one computer table, c = 2,671

The total amount needed to purchase the 16 computer tables is calculated as follows;

Total cost of 16 computer tables = cost of one computer table x total number of tables needed

Total cost of 16 computer tables = 2,671 x 16

Total cost of 16 computer tables = 42,736

Therefore, the total amount needed to purchase the 16 computer tables is 42,736

A user has a computer with a single SSD, and the entire drive contains one partition. The user wants to install a second OS on the computer without having to reinstall the current OS. The user wants to be able to select which OS to use when booting the computer. Which Disk Management tools should the user utilize to accomplish this task?

Answers

Answer:

The correct approach is "Shrink partition". A further explanation is given below.

Explanation:

Shrinking partition shrinks or decreases this same disc size as well as unallotted disc space, unallotted space could be utilized to mount a secondary Operating system to operate as a double operating system.Whilst also diminishing everything into neighboring volatile memory on another disc, this same space required for area as well as drives could also be reduced.

Thus the above is the correct answer.
