True or False: Cracking a Vigenère cipher with brute force takes longer than a Caesar cipher, but it is still a reliable method
iragen [17]

Answer:

False

Explanation:

The Vigenere cipher is an encryption method that uses a series of interwoven Ceaser ciphers and a keyword to encrypt text. The difference between this cipher and the Ceaser cipher is the tabular interwoven Ceaser cipher and the keyword.

Multiple keywords can be used in the Vigenere cipher. The use of this keyword makes the brute-force decipher algorithm unreliable for decoding text encrypted with it.

Computer A has an overall CPI of 1.3 and can be run at a clock rate of 600 MHz. Computer B has a CPI of 2.5 and can be run at a
kirill115 [55]

Answer:

Check the explanation

Explanation:

CPI means Clock cycle per Instruction

given Clock rate 600 MHz then clock time is Cー 1.67nSec clockrate 600M

Execution time is given by following Formula.

Execution Time(CPU time) = CPI*Instruction Count * clock time = \frac{CPI*Instruction Count}{ClockRate}

a)

for system A CPU time is 1.3 * 100, 000 600 106

= 216.67 micro sec.

b)

for system B CPU time is =\frac{2.5*100,000}{750*10^6}

= 333.33 micro sec

c) Since the system B is slower than system A, So the system A executes the given program in less time

Hence take CPU execution time of system B as CPU time of System A.

therefore

216.67 micro = =\frac{2.5*Instruction}{750*10^6}

Instructions = 216.67*750/2.5

= 65001

hence 65001 instruction are needed for executing program By system B. to complete the program as fast as system A
