Answer:

The correct option is np.array

Explanation:

Numpy is a library to perform numerical calculation in python. It allows us to create and modify vectors, and make operations on them easily. Numpy arrays are an excellent alternative to python lists. Some of the key advantages of numpy arrays are that they are fast, easy to work with, and offer users the opportunity to perform calculations through full arrays.

To start using numpy, the library must be imported:

import numpy as np

The most common way to create a vector or matrix already initialized is with the np.array function, which takes a list (or list of lists) as a parameter and returns a numpy matrix. The numpy arrays are static and homogeneous typing. They are more efficient in the use of memory.

Example:

list = [25,12,15,66,12.5]

v = np.array (list)

print (v)

What is the meaning of antimonographycationalis

Oliga [24]

Answer:

Although this word was made up in order to be a contender for the longest word in English, it can be broken down into smaller chunks in order to understand it.

Anti- means that you are against something; monopoly means the exclusive control over something; geographic is related to geography; and the remaining part has to do with nationalism.

So this word means something like 'a nationalistic feeling of being against geographic monopoly,' but you can see that it doesn't have much sense.

Assume that you are able to do an exhaustive search for the key to an encrypted message at the rate of 100 Million trials per se

Len [333]

Answer:

Following are the solution to this question:

Explanation:

In point 1:

Trials frequency $= \frac{100 \ million }{second}$

calculating the main length of cryptography = 112 bit

$\to 100\ Million = 1 \times 10^8$

calculating the second year value:

$\to 365 \times 24 \times 60 \times 60 =3153600\\\\$

$=3.15 \times 10^7 \ seconds$

Currently, in average , at least half the possible sleeves is being used to verify the encryption process: $2^{111} \ keys$

$\to \frac{2^{111} \time3s 10^6}{3.15 \times 10^7}\approx 8.22 \times 10^{20} \ years$

the total time value will be $8.22 \times 10^{20} \ years$

In point 2:

In cryptography, the common name is Triple DES (3DES), which would be the symmetric-key encrypted communication algorithm (TDEAor Triple DEA), which adds 3 times per block size only with the cryptographic method Data Encryption Standard ( DES).

Algorithm:-

The key package involves four DES keys, K1, K2, and K3, each 56-bit (except parity bits), Triple DES includes. Its encoding algorithm is::

$ciphertext = EK3(DK2(EK1(plaintext)))$

I.e. K1, DES encrypt, K2 decrypt, then K3 encrypt DES.

The reverse is the decryption:

$plaintext = DK1(EK2(DK3(ciphertext)))$

I.e. decrypt by K3, crypt by K2, decrypt by K1.

Every three-bit authentication encrypts a 64-bit block.

Its middle procedure in each situation it's the reverse of the first operation. It improves the strength of the key second option algorithm which offers DES native support with key option 3.
