What is the key distribution problem of the symmetric (secret) key encryption?

1 answer:

6 0

When encrypting content with a symmetric key, the receiving party needs to have this key in order to decrypt. However, there is a fundamental problem that the key itself cannot be easily shared with the receiver over an unsafe channel, where attackers could eavesdrop and capture it as well.

The solution for this is either to use asymmetric key encryption, or to use a key exchange algorithm such as the one devised by Diffie-Hellman.

A ____ attack is much more substantial than a DoS attack because of the use of multiple systems to simultaneously attack a singl

victus00 [196]

Answer: (D) Distributed denial- of- service (DDoS)

Explanation:

The distributed denial of service attack is one of the type of attack that occur when the multiple system are basically flooded with the resources and the bandwidth.

Botnet is one of the example of DDoS as it caused the DOS (denial of service) for the users.
This type of attack is more substantial as compared to the DoS attack as they use the multiple system for attack the single target simultaneously.

Therefore, Option (D) is correct.

the majority of refrigeration systems in residential comfort cooling systems use what type of system?

DIA [1.3K]

Air conditioning, or cooling, is more complicated than heating. Instead of using energy to create heat, air conditioners use energy to take heat away. The most common air conditioning system uses a compressor cycle (similar to the one used by your refrigerator) to transfer heat from your house to the outdoors.

Picture your house as a refrigerator. There is a compressor on the outside filled with a special fluid called a refrigerant. This fluid can change back and forth between liquid and gas. As it changes, it absorbs or releases heat, so it is used to “carry” heat from one place to another, such as from the inside of the refrigerator to the outside. Simple, right?

Well, no. And the process gets quite a bit more complicated with all the controls and valves involved. But its effect is remarkable. An air conditioner takes heat from a cooler place and dumps it in a warmer place, seemingly working against the laws of physics. What drives the process, of course, is electricity — quite a lot of it, in fact. Hope this helps?
