Question
Which security measure involves encoding data in such a way that only authorized parties can access it, rendering it unreadable to anyone else?
Solution
The security measure that involves encoding data in such a way that only authorized parties can access it, rendering it unreadable to anyone else, is called encryption.
Here are the steps involved in encryption:
-
Plain Text: This is the original readable data which needs to be encrypted for security purposes.
-
Encryption Algorithm: This is a method used to transform the plain text into cipher text. There are many types of encryption algorithms such as RSA, AES, DES, etc.
-
Encryption Key: This is a piece of code that is known only to the person who encrypts the data and the person who can decrypt it. The same key can be used for both encryption and decryption (symmetric encryption), or there can be two different keys for encryption and decryption (asymmetric encryption).
-
Cipher Text: This is the unreadable text that is generated after the encryption process. It can only be converted back to plain text by someone who has the decryption key.
-
Decryption: This is the process of converting the cipher text back into plain text using the decryption key.
So, in summary, encryption is the security measure that involves encoding data in such a way that only authorized parties can access it, rendering it unreadable to anyone else.
