Answer:
message confidentiality
Two or more hosts communicate securely, typically using encryption. The communication cannot be monitored (sniffed) by non trusted hosts. The communication between trusted parties is confidential.
message integrity
The message transported has not been tampered with or altered. A message has integrity when the payload sent is the same as the payload received.
Sending a message confidentially does not guarantee data integrity. Even when two nodes have authenticated each other, the integrity of a message could be compromised during the transmission of a message.
Yes, you can have integrity of a message without confidentiality. One can take a hash or sum of the message on both sides to compare. Often we share downloadable files and provide data integrity using md5 hash sums.
Explanation:
The programmers should keep lines of code short because It makes the code more readable by other programmers.
<h3>
Short lines of Code</h3>
Normally, a shorter lines of code are more efficient than spreading the code over several lines
Also, If a programmer have more lines of code, there are more places for bugs to hide and finding them might be more of a hassle.
So, the fewer lines of code can achieve the same results or much better than many lines of code
Hence, the programmers should keep lines of code short because It makes the code more readable by other programmers.
Therefore, the Option A is correct.
