Detailed Solution
Download Solution PDFThe correct answer is Cryptography is for masking message content; Steganography is for hiding the existence of the message itself.
Key Points
- Cryptography involves techniques used to secure communication in the presence of third parties by transforming the message into an unreadable format, known as encryption.
- The primary goal of cryptography is to ensure confidentiality, integrity, authenticity, and non-repudiation of the message.
- Steganography is the practice of concealing a message, image, or file within another message, image, or file so that the presence of the hidden message is not detected.
- The main purpose of steganography is to hide the existence of the communication, rather than the content itself.
- Both cryptography and steganography are used for information security, but they serve different purposes.
Additional Information
- Option A: Cryptography is for translation; Steganography is for dictation
- This statement is incorrect. Cryptography is not about translation but about securing message content through techniques like encryption.
- Steganography is not about dictation but about concealing the existence of messages.
- Option B: Cryptography is for masking message content; Steganography is for dictation
- This statement is partially correct but incorrect regarding steganography. While cryptography does mask the message content, steganography is not related to dictation but to hiding the existence of the message.
- Option C: Cryptography is for masking message content; Steganography is for hiding the existence of the message itself
- This statement is correct.
- Cryptography focuses on transforming the message so that it is unreadable without the proper decryption key.
- Steganography aims to make the message itself undetectable by embedding it within another medium.
