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?
With a block cipher the algorithm works on chunks of data—encrypting one and then moving to the next.
Example: Blowfish is an encryption system that performs a 64-bit block cipher at very fast speeds.
One Comment on “Which of the following has Sara selected?”
“A stream cipher is an encryption algorithm that encrypts 1 bit or byte of plaintext at a time”. So, correct answer is B
