sender needs to send the four data items: 0x3456, 0xABCC,0x02BC, and 0xEEEE.


1. What is the checksum at the sender site, receiversite (if there is no error)?


2. What is the checksum at the receiver site if thesecond data item is changed to 0xABCE?


3. What is the checksum at the receiver site if thesecond data item is changed to 0xABCEand            the third data item is changed to 0x02BA?


I don't understand how to formulate the items to get achecksum at the sender or receiver site?

1. A company that wants to send data over the Internet will use an encryption program to ensure data security. All data will be transmitted as four-digit integers. The application should read a four-digit integer entered by the user and encrypt it as follows:  Replace each digit with the remainder of the new value divided by 10 by adding 6 to the digit. Then replace the number in the first digit with the third, and the number in the...

When encrypting data, we must ensure that both the sender and the receiver are in possession of the correct keys to allow them to either encrypt or decrypt the messages successfully. There are two main types of encryption defined by the number of different keys used. (10 marks total) i. Name each type and briefly explain how they are different? ii. Name one popular algorithm used for each type of encryption. iii. A user would like to send a long,...
