I won't report. Thanks for the points
Explanation:
<span>a. DA
Given the question and available options, this looks like a question about Ethernet frames. So let's look at the options and see what makes sense.
a. DA
* DA - Destination address. And the question pretty much defines what it is. So this is the correct choice.
b. SA
* SA - Source address. This is the physical address that the frame was sent from. And since the question is mentioned who the frame is intended for, this is obviously the wrong choice.
c. SFD
* SFD - Start Frame Delimiter. This is a special CONSTANT sequence of bits that terminates the preamble. It's purpose is to indicate the start of the frame payload. Since it's a constant value, it does not indicate in any way where the frame is intended to go. So this is a bad choice.
d. Preamble
* Preamble - is a pattern of alternating 0 and 1 bits intended to synchronize receivers so that the rest of the frame is interpreted correctly. This too is a constant value and as such can't indicate the destination of the frame, so it's a bad choice.</span>
<span>The answer is : Increasing the key length of DES would protect it against brute force attacks. </span>Brute force is when the attacker tries every key knowing that one will eventually work. <span>Key length increase proportionally increases the key space, having a keyspace l</span>arge enough that it takes too much time and money to accomplish a brute force attack.
