Answer:
The answer is "secret key k".
Explanation:
When the sender sends the message, he/she may combine, it with the hidden key, and determines the hashing, when transmitting the information the digest is being sent, and also the message is transmitted through the connection.
when the receiver receives the message, still having the very same secret key, adding the Hidden Key then recalculating the hashing again. In this, two factors if another subsequent digest matches something, this message is sent.
- During transit, the message was certainly not changed.
- Anybody with the private key – preferably even a preferred sender sent out this letter.
Answer: Information

Answer:
It is done to avoid collision among the channel.
Explanation:
CSMA/CD stands for carrier sense multiple access/collision detection.
It is a media access protocol that tells the devices how to respond when a channel is used simultaneously by two devices. The main purpose is to manage the transmission when a collision is encountered.
In the given scenario when the channel is detected idle, the station does not transmits second frame in order to avoid collision. CSMA/CD protocol is designed so that after transmission of first frame, second frame transmission is started at step 2 instead of step 1.
Following is given the flow chart that depicts the working of the protocol CSMA/CD:
