Case Study 6

Secure Data Transmission: Secure data transmission means that data/information is not being received or modified by an unauthorised person, over a network, from source to destination. For secure data transmission, we can convert an ‘ actual message (which is in readable form) into an unreadable message (called an encrypted message) with the help of the concept of encryption. This unreadable message is sent through the network to the destination. If a hacker tries to read this message, he/she receives an unreadable message that cannot be easily converted into the actual message.

The unreadable message can be converted to the original message by the receiver at the destination. Caesar Cipher is one of the common encryption techniques. In this technique, each letter of the word is replaced by a letter some fixed number of positions (usually called as key) down the alphabet. For example, if the key is 3, each ‘A’will be replaced by ‘D’ (Letter ‘D’ is 3 positions down Letter A’ in the alphabet), each‘B’will be replaced by ‘E’ and similarly, each‘Z’ will be replaced by‘C. The receiver can identify the original message by using the reverse technique of encryption. This reverse technique is called decryption.

(a) Secure data transmission means:

(i) data can be accessed by any unauthorised person during transmission
(ii) data cannot be accessed by any unauthorised person during transmission
(iii) transmission of data
(iv) None of the above

(iv) All of these

(c) Caesar Cipher is:

(i) used for conversion of the actual message into an encrypted message
