Question

Difficulty: EasyInformation Technology and Cybersecurity

In symmetric key cryptography, the sender and the recipient use two distinct keys—a public key for encrypting data and a private key for decrypting data.

Answer: Answer

Answer

The statement is False. Symmetric key cryptography relies on a single shared secret key for both encryption and decryption, whereas asymmetric key cryptography uses a public-private key pair.
The statement is false because symmetric key encryption algorithms (such as AES or DES) employ a single secret key shared between the sender and receiver for both encryption and decryption. A public and private key pair is used exclusively in asymmetric key cryptography (such as RSA or ECC).

Step-by-Step Solution

1
Analyze the core definition of symmetric key cryptography.
Symmetric key cryptography uses the exact same key to both encrypt and decrypt information.
Establishing foundational cryptographic terminology.
2
Compare the statement's description with cryptographic definitions.
The statement describes public-key (asymmetric) cryptography, not symmetric key cryptography.
Differentiating symmetric encryption from asymmetric key pair mechanisms.
