Encryption and Cryptography Flashcards

What does AES stand for in cryptography?

Answer: Advanced Encryption Standard

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

What is RSA primarily used for in cryptography?

Answer: Asymmetric encryption and digital signatures

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

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

Answer: Encryption where only the communicating parties can read the messages

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.

What is a cryptographic hash function primarily used for?

Answer: Creating a fixed-size digital fingerprint of data

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

What does PKI stand for?

Answer: Public Key Infrastructure

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

Which protocol is used to establish an encrypted connection between a web browser and a server?

Answer: TLS/SSL

TLS (Transport Layer Security), formerly known as SSL, establishes encrypted and authenticated connections between clients and servers.

What is a digital signature used to verify?

Answer: The authenticity and integrity of a digital message or document

A digital signature authenticates the sender's identity and confirms the message or document has not been altered since it was signed.
