Answer:
B. False.
Explanation:
Cryptanalysis can be defined as the study, art or process of evaluating and analyzing information systems such as ciphertext, cryptographic systems and ciphers. The main purpose of Cryptanalysis is for a better understanding of how the cryptographic system works, in order to find techniques for deciphering, defeating or weakening them without an access to any privileged or secret data (information) required to do so.
Hence, cryptanalysis is made more difficult by having longer keywords as opposed to having shorter keywords which typically would make it easier for an attacker to decipher.
In a nutshell, it is false and incorrect to say that cryptanalysis is made more difficult by having shorter keywords.
Answer:
def encrypt_digit(digit):
if type(digit) is int or float:
digit = str(digit)
hold = list()
for x in digit:
d = str((int(x) + 3)%10)
hold.append(d)
first = hold.pop(0)
second = hold.pop(0)
third = hold.pop(0)
fourth = hold.pop()
print(int("".join([third,fourth, first, second])))
encrypt_digit(7836)
Explanation:
The python function accepts a four-digit parameter which represents the data transmitted over the company's telephone network. The function encrypts the data by adding 3 to each digit and getting the modulus of division 10, then the digits are swapped and printed out encrypted and ready for transmission.
Answer:
a) Internal Forwarding is not used = 26 clock cycles
b)Internal Forwarding is used= 22 clock cycles
The man utility is a console based program that displays manual pages of other utilities, so for fdisk, you would use man -k fdisk to search for fdisk related manuals
