I dont think it would be possible for someone to listen to your calls im pretty sure only the police could if they provide a sign warrent by a judge to the phone company
No it will actually help it
Answer:
See explaination
Explanation:
2a)
A hacker group hacked into the Bay Area Rapid Transit system, this was done to protest BART’s shut down of wireless communication in some BART stations. Such attacks is done mostly to stand for some situation which happened previously. Hence, we can say it is a form a hacktivism. It was not ethical as it disrupted the system for some time.But this is also a form of protest which is been done by some group of peoples.
2b)
If a foreign government launches a hacking attack, it can be considered a war.
If this type of attack happens then the repercussions may result to the war.
2c)
We gave an analogy between merchants accepting some amount of shoplifting, on the one hand, and merchants and credit card companies accepting some amount of credit card fraud, on the other hand.
THe streght so called can be pointed out as the money is rolling in the market and the business keeps on going.
The weakness can be described as the loss which is being incurred by the company.
Answer: (C) MAC
Explanation:
MAC is stand for the message authentication code and it is one of the key dependent hash function. Message authentication provide the data integrity and also the origin of data authentication.
- It basically allow the specific recipients known as the holder of the symmetric key.
- The message authentication code uses the CBC (Cipher block chaining) mode for constructing the MAC algorithm and it also uses the block cipher for the conjunction by using the CBC operations.
On the other hand, all the options are incorrect as they are not the key dependent hash function.
Therefore, Option (C) is correct.
Explanation:
We can divide the multiplex in different categorize, for example:
- FREQUENCY DIVISION MULTIPLEXERS (FDM)
-
TIME DIVISION MULTIPLEXERS (TDM)
-
STATISTICAL TIME DIVISION MULTIPLEXERS (STDM).
But in this case, we're going to explain about the time and frequency, because the time division multiplex differ to frequency, because the circuit is divided horizontally, and the time is vertically
b. splits the communication circuit vertically (with time slots) instead of horizontally
