Question

Unit 7

1 List three examples in which digital data is encrypted for security purposes.

Answer 1

Now let's see the three different encryption examples which involves ith three different methods.
- Data can be encrypted by using Hashing. By using this method data cannot be tampered. Each hash is unique to a specific message. Authentication protocols must be needed so that the data will not be hacked.
- Symmetric method that means it works with the key. so the key is used to encrypt or decrypt the data to make the data secure. If you want to send any file you use a particular key for it and receiver also uses the same key to take back the file.
- Asymmetric method is also based with the key but it will have a common key for the encryption but decryption must be needed the particular key to use the data
