TOPIC 1: CRYPTOGRAPHIC FUNDAMENTALS
10 Questions • 10.0% of Exam • This topic covers the essential concepts and mechanisms of cryptography used for securing data.
QUESTION 1
Public key infrastructure (PKI)
Answer: A system that manages the creation, distribution, and revocation of digital certificates.
Rationale: PKI provides the framework for verifying identities and securing communications through the lifecycle
management of digital certificates, encompassing their issuance, distribution, and revocation. This infrastructure underpins
trust in digital interactions by ensuring the authenticity and integrity of cryptographic keys.
QUESTION 2
Public key
Answer: A cryptographic key that is used for encryption and verifying digital signatures in asymmetric
encryption.
Rationale: A public key is part of an asymmetric cryptographic system, enabling anyone to encrypt messages or verify
signatures, but only the corresponding private key can decrypt or create signatures. This asymmetry ensures secure
communication and authentication without needing to share a secret key.
QUESTION 3
Private key
Answer: A cryptographic key that is used for decryption and creating digital signatures in asymmetric
encryption.
Rationale: The private key is uniquely paired with a public key in asymmetric cryptography and is kept secret by its owner to
decrypt messages encrypted with the corresponding public key and to generate digital signatures verifying authenticity. This
principle underscores asymmetric encryption's core function of secure communication and authentication through key pair
management.
