Cryptography and Steganography are two distinct yet deeply complementary methods used in information security to protect data during transmission and storage. While they approach data protection from entirely different angles, combining them creates a highly secure, multi-layered defense mechanism.
Here is a comprehensive breakdown of how these two fields operate, differ, and work together. Core Concepts 1. Cryptography (Secret Writing)
Cryptography focuses on scrambling the content of a message to make it unreadable to unauthorized parties.
The Goal: To prevent an adversary from understanding the information.
How it works: It uses mathematical algorithms and cryptographic keys to convert plain text into unreadable ciphertext. Even if an attacker intercepts the data, they cannot easily decipher it without the proper key.
Limitation: Encrypted data is highly visible. It looks like random, garbled text or code, which immediately flags to an attacker that secret or valuable data is being transmitted. 2. Steganography (Covered Writing)
