A network stream needs to be encrypted. Sara, the network administrator, has selected a cipher
which will encrypt 8 bits at a time before sending the data across the network. Which of the
following has Sara selected?
A.
Block cipher
B.
Stream cipher
C.
CRC
D.
Hashing algorithm
Who on earth is using an 8-bit block cipher? DES, 3DES, and Blowfish all use 64-bit blocks, which is the shortest that my book mentions.
I think the answer should be stream cipher, which encrypts data a single bit or single byte at a time.
