Answer:

The correct answer is letter "A": The message is broken into independent blocks which are encrypted.

Explanation:

There are five (5) main forms of encryption: <em>Electronic Code Book (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB), and Output Feedback (OFB)</em>. Electronic Code Book (ECB) is the simplest of all of them. Using this method to encrypt information implies dividing a message into two parts to encrypt each block independently. ECB does not hide patterns effectively because the blocks are encrypted using identical plaintexts.

motikmotik

Answer:

a=[23,6,78,36,3,250,127,210,-5]

i = len(a) # calculate length

j = min(a) # calculate minimun

k = sum(a) # calculate sum

l= sum(a)/len(a)  # calculate mean

print(i)

print(j)

print(k)

print(l)

z = 0.0

i=0

x=[23,6,78,36,3,250,127,210,-5]

y = int(l)

while x[i] < y:  

   z= int(x[i]/y)

   print(z)

   x[i] = x[i] - y

   z=z+1

   i=i+1

Explanation:

So above we have calculated Count, minimum, sum and mean/average. Also we did a simple division and printed quotient.
