Which concept is a discipline of math and computer science concerned with information security, particularly encryption and authentication?

• A. Consumer
• B. Data-Flow Diagram
• C. Cryptography
• D. CVSS

Answer: (C)

Cryptography is the discipline of math and computer science focused on securing information, including encryption and authentication. It builds algorithms and protocols that transform readable data into unreadable form and back, using cryptographic keys. It covers symmetric encryption (same key for encryption and decryption) and asymmetric encryption (public/private keys), as well as hash functions and digital signatures. These tools enable confidentiality (keeping data secret), integrity (detecting tampering), and authenticity (verifying identities). In practice, cryptography underpins secure communications, protected storage, and reliable user authentication. The other terms are not security disciplines: a data-flow diagram models how data moves through a system, CVSS rates vulnerability severity, and consumer is simply a user or customer.
