C1 Cryptography & Encryption

This terms is derived from the Greek work kryptos, meaning hidden or secret.

• Chronological

• Cryogenics

• Encryption

• Steganography

This person develops strong solutions to provide data security.

• Cartographer

• Computer forensic analyst

• Cryptanalyst

• Cryptographer

Name for when both peers agree that the other is who they claim to be.

• Multifactor authentication

• Mutual authentication

• Twofish authentication

• Access authorization

When physics is used instead of mathematics in a cipher process, it is called what?

• Biometric cryptology

• Physical cryptology

• Quantum cryptology

• Physical encryption

This type of cipher mixes a number of ciphertext alphabets in the cryptogram so each plain letter text is continuously changed.

• Monoalphabetic substitution cipher

• Polyalphabetic substitution cipher

• Rotating substitution cipher

• Bilateral substitution cipher

This type of encryption uses a single, pre-shared key to encrypt and decrypt data.

• Asymmetric encryption

• Symmetric encryption

• Quantum encryption

• Elliptical-curve encryption

The combination of symmetric and asymmetric encryption that is used to keep Internet banking and e-commerce transactions secure is called this.

• Quantum encryption

• Elliptical-curve encryption

• Hybrid encryption

• Twofish encryption

One of the earliest recorded ciphers is

• Vigenere

• Atbash

• Enigma

• Pigpen

This is an example of a stream cipher.

• Rivest/RC4

• Blowfish

• Diffie-Hellman

• Data Encryption Standard (DES)

  
  

This method of hiding data involves shrinking an image to the size of a period.

• Microdot

• Nanopoint

• Steganography

• Enigma
