Encryption

This uses a public ledger

• CSP

• Bitcoin

• RC4

• Quantum Encryption

Which determines the method of encryption?

• SSL

• A server

• CSP

• OCSP

A teeny reduced portion of an image is placed on a document to make data not readable. What is this?

• Atbash cipher

• microdot

• Pigpen cipher

• watermark

This allows a CA to identify if a certificate is good for subsequent requests.

• CRL

• CSP

• OCSP Pinning

• OCSP Stapling

This can increase the time it takes to try and break a password

• Hash

• rainbow table

• Dictionary word list

• Salt

A company handles a great deal of financial information. What can they do to ensure access to a private key if a current employee steals the key?

• key escrow

• Salting the key

• incorporate confusion

• Lower the crypto period

You don't want a compromised key to open old transactions. This is the principle behind:

• Obsfucation

• PRNG

• Confusion

• Perfect forward secrecy

Which of these is not a symmetric key?

• Diffie Hellman

• ECC

• 3DES

A becomes Z, B becomes Y etc. This is an example of:

• A transposition cipher

• A substitution cipher

• A polyalphabetic cipher

• A symmetric cipher

Pigpen is an example of:

• An enigma version

• A symmetric encryption

• A substitution cipher

• A Mono-alphabetic cipher
