CASE CASE Cryptography & Data Protection 2

Question 1

Which password hashing function is recommended for secure storage due to its adaptive work factor?

Accepted Answer

bcrypt

Answer

bcrypt is a password hashing function with a configurable work factor that makes brute-force attacks computationally expensive.

Question 2

What is the primary purpose of a digital certificate?

Accepted Answer

Binding a public key to a verified entity identity

Answer

A digital certificate binds a public key to the identity of an entity, verified and signed by a trusted Certificate Authority.

Question 3

What role does a Certificate Authority (CA) play in PKI?

Accepted Answer

Issues, signs, and manages digital certificates

Answer

A Certificate Authority issues and digitally signs certificates, establishing a chain of trust for public key validation.

Question 4

What does cryptographic key management encompass?

Accepted Answer

Administering keys through their full lifecycle including generation, storage, rotation, and destruction

Answer

Key management covers the entire cryptographic key lifecycle: generation, distribution, storage, rotation, and secure destruction.

Question 5

Which cryptographic property ensures a sender cannot deny having transmitted a message?

Accepted Answer

Non-repudiation

Answer

Non-repudiation prevents an originator from denying having sent a message, typically enforced through digital signatures.
