A strategy for concealing critical information as well as ensuring its secure communication everything in non-hidden storage is steganography.

Advantage:

Because the content is contained throughout a non-secure file, the above strategy decreases the chance of an assault on classified info.

Disadvantage:

This approach has the disadvantage that concealed information might be able to retrieve if somehow the documents have been changed or deleted as of a non-secure file.

Once again to encrypt as well as decode information, symmetric encryption employs a unique key, but asymmetric encryption utilizes two different keys, something for encryption as well as someone else for decryption.

Advantage:

One such approach is superior to steganography throughout the level of protection.

Disadvantage:

Because distinct keys have been needed to get access, such techniques of asymmetric encryption are considerably slower.

Thus the approach above is correct.

Answer from: amarshall90

Explanation:

Steganography is a technique used in securing or hiding sensitive information by encrypting the information in a non-hidden file like a JPEG format. A major advantage of this method is that it reduces the risk of attack or break-in since the data is enclosed in a non-secure file; thereby reducing threats of any hack. One main disadvantage of this method is that the hidden message may become difficult to recover if the source file (non-secure file) used, is edited or deleted.

In symmetric or asymmetric encryption they both employ cryptographic encryption method. While symmetric encryption uses one key to encrypt and decrypt data, asymmetric encryption uses two keys (one for encryption, the other for decryption) of the data. A major advantage of using these methods is that they provide more security. Although while symmetric encryption is faster, asymmetric encryption is slower (eg using separate keys to gain access), a disadvantage.

Write a pseudocode solution for each of these problems. 1. design a while loop that lets that user enter a number. the number should be multiplied by 10, and the result stored in a variable named product. the loop should iterate as long as product contains a value less than 100. 2. design a do-while loop that asks the user to enter two numbers. the numbers should be added and the sum displayed. the loop should ask the user whether he or she wishes to perform the operation again. if so, the loop should repeat; otherwise it should terminate. 3. design a for loop that displays the following set of numbers: 0, 10, 20, 30, 40, 50 100. 4. design a nested loop that displays 10 rows of # characters. there should be 15 # characters in each row. 5. convert this for loop to a while loop. declare integer count for count = 1 to 50 display count end for 6. find the error in the following pseudocode. declare boolean finished = false declare integer value, cube while not finished display “enter a value to be cubed.” input value; set cube = value ^ 3 display value, “ cubed is “, cube end while
