CSCU Encryption and Cryptography 2

Question 1

What does AES stand for in cryptography?

Accepted Answer

Advanced Encryption Standard

Answer

AES (Advanced Encryption Standard) is a widely adopted symmetric encryption algorithm standardized by NIST and used by the US government.

Question 2

What is RSA primarily used for in cryptography?

Accepted Answer

Asymmetric encryption and digital signatures

Answer

RSA is an asymmetric cryptographic algorithm used for secure data transmission and creating digital signatures.

Question 3

What is end-to-end encryption (E2EE)?

Accepted Answer

Encryption where only the communicating parties can read the messages

Answer

E2EE ensures that data is encrypted on the sender's device and can only be decrypted by the intended recipient, with no one in between able to read it.

Question 4

What is a cryptographic hash function primarily used for?

Accepted Answer

Creating a fixed-size digital fingerprint of data

Answer

Hash functions produce a fixed-length digest (fingerprint) of data, used to verify data integrity since any change to input produces a different hash.

Question 5

What does PKI stand for?

Accepted Answer

Public Key Infrastructure

Answer

PKI (Public Key Infrastructure) is the framework of policies, hardware, software, and procedures used to manage digital certificates and public-key encryption.
