source

Denyi ng - opposite of gainin g access

Limiting - allowin g so me access to our resour ce , only up to a cert ain point

Revoking - ta kes access away from former user



AES –

CORRECT ANSWE R: uses three different ciphers : one with a 128 - bit key , one

with a 192 - bit key , and one with a 25 6 - bit key , all hav ing a block length of 128

bits



Asymmetri c cryptography –

CORRECT ANSWE R: a public key and a pr ivate key . The public key is used to

encrypt d ata sent from the sender to the r eceiver and is shared with every one .

Private keys are used to decrypt d ata that arrives at t he receivin g end and are

very carefully guarded by the receive ( aka the public key cryptography )
