Which data security component is provided by hashing algorithms?key exchangeconfidentialityauthenticationintegrityNavigation Bar
Solution
Hashing algorithms provide the data security component of "integrity".
Here's a step-by-step explanation:
-
Hashing is a process that takes an input (or 'message') and returns a fixed-size string of bytes, typically a 'digest' that is unique to each unique input.
-
The main use of a hash function in cryptography is to verify the integrity of any data.
-
Integrity in data security means maintaining the consistency, accuracy, and trustworthiness of data over its entire life cycle.
-
When data is sent from one place to another, it may be vulnerable to some form of alteration. By creating a hash of the data, you can later compare it with the hash of the received data.
-
If the hashes match, it means the data was not tampered with during transmission. If they don't match, it means the data's integrity has been compromised.
-
Therefore, hashing algorithms provide the data security component of integrity.
